Subject: git-svn: multi-init saves and reuses --tags and --branches arguments
X-Git-Tag: v1.4.3-rc3~18
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c35b96e7851e417a24c1e255e353c67b31955466;p=git.git

git-svn: multi-init saves and reuses --tags and --branches arguments

This should make it much easier to track newly added tags and
branches.  Re-running multi-init without command-line arguments
should now detect new-tags and branches.

--trunk shouldn't change often, but running multi-init on it
is now idempotent.
