Subject: Ignore funny refname sent from remote
X-Git-Tag: v0.99.9~118
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=1a7141ff28e217312da4b289127875905c6ec479;p=git.git

Ignore funny refname sent from remote

This allows the remote side (most notably, upload-pack) to show
additional information without affecting the downloader.  Peek-remote
does not ignore them -- this is to make it useful for Pasky's
automatic tag following.
