Subject: git-svn: don't allow commit if svn tree is not current
X-Git-Tag: v1.4.1-rc1~26^2~17^2~20
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=b63af9b340dd831840c70103c9f609940a910031;p=git.git

git-svn: don't allow commit if svn tree is not current

If new revisions are fetched, that implies we haven't merged,
acked, or nacked them yet, and attempting to write the tree
we're committing means we'd silently clobber the newly fetched
changes.
