Revision 52f28529f4f90cebdca47f8eacbff5cb20004bed authored by Junio C Hamano on 13 July 2005, 19:45:51 UTC, committed by Linus Torvalds on 13 July 2005, 19:55:07 UTC 
[PATCH] git-diff-*: --name-only and --name-only-z.
 
Porcelain layers often want to find only names of changed files,
and even with diff-raw output format they end up having to pick
out only the filename.  Support --name-only (and --name-only-z
for xargs -0 and cpio -0 users that want to treat filenames with
embedded newlines sanely) flag to help them.

/* Help to copy the thing properly quoted for the shell safety.

 * expected to enclose the result within a single quote pair.

 * E.g.
 *  original     sq_quote     result
 *  name     ==> name      ==> 'name'
 *  a b      ==> a b       ==> 'a b'
 *  a'b      ==> a'\''b    ==> 'a'\''b'
