Subject: Fix push with refspecs containing wildcards
X-Git-Tag: v1.5.3-rc0~137^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=6e66bf3c7953d68a5a2d57300e0f9077cf1767bf;p=git.git

Fix push with refspecs containing wildcards

Otherwise

    git push 'remote-name' 'refs/heads/*:refs/remotes/other/*'

will consider references in "refs/heads" of the remote repository
"remote-name", instead of the ones in "refs/remotes/other", which
the given refspec clearly means.
