Subject: [PATCH] Start adding the $GIT_DIR/remotes/ support.
X-Git-Tag: v0.99.5~2^2~11
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=ac4b0cff00b7629657e61a1d6e1f1a1250d03198;p=git.git

[PATCH] Start adding the $GIT_DIR/remotes/ support.

All the necessary parsing code is in git-parse-remote-script;
update git-push-script to use it.
