Subject: git-fetch: Don't trigger a bus error when given the refspec "tag"
X-Git-Tag: v1.5.5~9
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=f53423b0e09d0de9584f72ac298bdfdc9e886d73;p=git.git

git-fetch: Don't trigger a bus error when given the refspec "tag"

When git-fetch encounters the refspec "tag" it assumes that the next
argument will be a tag name. If there is no next argument, it should
die gracefully instead of erroring.
