Subject: remote-bzr: add option to specify branches
X-Git-Tag: v1.8.3-rc2~11^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=248663c4ff931f1f42fb7f8233d0ae23f80c7835;p=thirdparty%2Fgit.git

remote-bzr: add option to specify branches

We might not want all the branches. And branch handling in bazaar is
rather tricky, so it's safer to simply specify them.
