Revision 50b8e355b64c93a71d5008557e15f52c032240ff authored by Chris Shoemaker on 28 October 2005, 17:04:49 UTC, committed by Junio C Hamano on 28 October 2005, 20:37:38 UTC
Update docs and usages regarding '-r' recursive option for git-diff-tree. Remove '-r' from common diff options, mention it only for git-diff-tree. Remove one extraneous use of '-r' with git-diff-files in get-merge.sh. Sync the synopsis and usage string for git-diff-tree.

/*
* I'm tired of doing "vsnprintf()" etc just to open a
* file, so here's a "return static buffer with printf"
* interface for paths.
*
* It's obviously not thread-safe. Sue me. But it's quite
* useful for doing things like
*
* f = open(mkpath("%s/%s.git", base, name), O_RDONLY);
*
* which is what it's designed for.
