Subject: git-svn: --branch-all-refs / -B support
X-Git-Tag: v1.4.1-rc1~26^2~17^2~18
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=bf78b1d89b29f8524ccfbd7042fa277277e316ff;p=git.git

git-svn: --branch-all-refs / -B support

This should make life easier for all those who type:

	`git-rev-parse --symbolic --all | xargs -n1 echo -b`

every time they run git-svn fetch.
