 NAME
 ----
-git-stripspace - Filter out empty lines
+git-stripspace - Remove unnecessary whitespace
 
 
 SYNOPSIS
 --------
 [verse]
-'git stripspace' [-s | --strip-comments] < <stream>
+'git stripspace' [-s | --strip-comments] < input
 
 DESCRIPTION
 -----------
-Remove multiple empty lines, and empty lines at beginning and end.
+
+Clean the input in the manner used by 'git' for text such as commit
+messages, notes, tags and branch descriptions.
+
+With no arguments, this will:
+
+- remove trailing whitespace from all lines
+- collapse multiple consecutive empty lines into one empty line
+- remove empty lines from the beginning and end of the input
+- add a missing '\n' to the last line if necessary.
+
+In the case where the input consists entirely of whitespace characters, no
+output will be produced.
+
+*NOTE*: This is intended for cleaning metadata, prefer the `--whitespace=fix`
+mode of linkgit:git-apply[1] for correcting whitespace of patches or files in
+the repository.
