Subject: git-svn: correctly handle packed-refs in refs/remotes/
X-Git-Tag: v1.5.0-rc0~136
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=c53d696bcc2894b0df277e617740b15bac794df9;p=git.git

git-svn: correctly handle packed-refs in refs/remotes/

We now use git-rev-parse universally to read refs, instead
of our own file_to_s function (which I plan on removing).
