However, that function does not consider the space to be a
character which requires quoting, so let's special-case the
space inside print_path(). This will cause space-containing
paths to also be quoted in other commands where such quoting
is not strictly necessary, but it does not hurt to do so.
The test from 6280dfdc3b did not detect this because, while

Demonstrate git-show is broken with ranges
The logic of git-show has remained largely unchanged since around 5d7eeee (git-show: grok blobs, trees and tags, too, 2006-12-14): start
a revision walker with no_walk=1, look at its pending objects and
handle them one-by-one. For commits, this means stuffing them into a
new queue all alone, and running the walker.
Then Linus's f222abd (Make 'git show' more useful, 2009-07-13) came
along and set no_walk=0 whenever the user specifies a range. Which
appears to work fine, until you actually prod it hard enough, as the
preceding commit shows: UNINTERESTING commits will be marked as such,
but not walked further to propagate the marks.
Demonstrate this with the main tests of this patch: 'showing a range
walks (Y shape)'. The Y shape of history ensures that propagating the
UNINTERESTING marks is necessary to correctly exclude the main1
commit. The only example I could find actually requires that the
negative revisions are listed later, and in this scenario a dotted
range actually works. However, it is easy to find examples in git.git
where a dotted range is wrong, e.g.
While there, also test a few other things that are not covered so far:
the -N way of triggering a range (added in 5853cae, DWIM 'git show -5'
to 'git show --do-walk -5', 2010-06-01), and the interactions of tags,

do not run pager with diff --no-index --quiet
There is no point in running a pager when --quiet is given,

handles this already, because --quiet implies --exit-code,

pager.
However, the "quiet implies exit-code" logic is done in
diff_setup_done, and the no-index code path sets up its
pager before running diff_setup_done, and misses this case.
We can fix this by reordering our initialization.
Currently we do:
1. read command line arguments into diff_options
2. Set pager if EXIT_CODE not requested
3. always set EXIT_CODE, since we are emulating
traditional diff
4. call diff_setup_done
We can fix the problem by moving pager initialization (step
2) after step 4. But step 3 must come after step 2 (since we
want to know whether the _user_ requested --exit-code, not
whether we turned it on unconditionally). So we must move
both.

git-svn: use YAML format for mergeinfo cache when possible
Since v1.7.0-rc2~11 (git-svn: persistent memoization, 2010-01-30),
git-svn has maintained some private per-repository caches in
.git/svn/.caches to avoid refetching and recalculating some
mergeinfo-related information with every "git svn fetch".
These caches use the 'nstore' format from the perl core module
Storable, which can be read and written quickly and was designed for
transfer over the wire (the 'n' stands for 'network'). This format is
endianness-independent and independent of floating-point
representation.
Unfortunately the format is *not* independent of the perl version ---
new perl versions will write files that very old perl cannot read.
Worse, the format is not independent of the size of a perl integer.
So if you toggle perl's use64bitint compile-time option, then using
'git svn fetch' on your old repositories produces errors like this:
Byte order is not compatible at ../../lib/Storable.pm (autosplit
into ../../lib/auto/Storable/_retrieve.al) line 380, at
/usr/share/perl/5.12/Memoize/Storable.pm line 21
That is, upgrading perl to a version that uses use64bitint for the
first time makes git-svn suddenly refuse to fetch in existing
repositories. Removing .git/svn/.caches lets git-svn recover.
It's time to switch to a platform independent serializer backend with
better compatibility guarantees. This patch uses YAML::Any.
Other choices were considered:
- thawing data from Data::Dumper involves "eval". Doing that without
creating a security risk is fussy.
- the JSON API works on scalars in memory and doesn't provide a
standard way to serialize straight to disk.
YAML::Any is reasonably fast and has a pleasant API. In most
backends, LoadFile() reads the entire file into a scalar anyway and
converts it as a second step, but having an interface that allows the
deserialization to happen on the fly without a temporary is still a
comfort.
YAML::Any is not a core perl module, so we take care to use it when
and only when it is available. Installations without that module
should fall back to using Storable with all its quirks, keeping their
cache files in
.git/svn/.caches/*.db
Installations with YAML peacefully coexist by keeping a separate set
of cache files in
.git/svn/.caches/*.yaml.
In most cases, switching between is a one-time thing, so it doesn't
seem worth the complication to migrate existing caches.
The upshot: after this patch, as long as YAML::Any is installed you
can move your git repository between machines with different perl
installations and "git svn fetch" will work fine. If you do not have
YAML::Any, the behavior is unchanged (and in particular does not get
any worse).

git-svn: make Git::SVN::RA a separate file
This slices off another 600 or so lines from the frighteningly long
git-svn.perl script.
The Git::SVN::Ra interface is similar enough to SVN::Ra that it is
probably safe to ignore most of its implementation on first reading.
(Documenting or moving functions that do not fit that pattern is left
as an exercise to the interested reader.)

git-svn: make Git::SVN::Editor a separate file
This makes the git-svn script shorter and less scary for beginners to

revision: note the lack of free() in simplify_merges()
Among the three similar-looking loops that walk singly linked
commit_list, the first one is only peeking and the same list is
later used for real work. Leave a comment not to mistakenly
free its elements there.
The code internally runs sort_in_topo_order() already; it is more clear
to spell it out in the option parsing phase, instead of adding a special
case in simplify_merges() function.

docs: fix cross-directory linkgit references
Most of our documentation is in a single directory, so using
linkgit:git-config[1] just generates a relative link in the
same directory. However, this is not the case with the API
documentation in technical/*, which need to refer to
git-config from the parent directory.
We can fix this by passing a special prefix attribute when building
in a subdirectory, and respecting that prefix in our linkgit
definitions.
We only have to modify the html linkgit definition. For
manpages, we can ignore this for two reasons:
1. we do not generate actual links to the file in
manpages, but instead just give the name and section of
the linked manpage
2. we do not currently build manpages for subdirectories,
only html

fmt-merge-msg: make attribution into comment lines
The submaintainer credit is not something you can compute purely by
looking at the history and its shape, especially in the presense of
fast-forward merges, and this observation makes the information on
the "via" line unreliable. Let's leave the final determination of
credits up to whoever is making the merge and show them as comments.

unpack-trees.c: use path_excluded() in check_ok_to_remove()
This function is responsible for determining if a path that is not
tracked is ignored and allow "checkout" to overwrite it as needed.
It used excluded() without checking if higher level directory in the
