git-svn: loosen config globs limitations

Expand the area of globs applicability for branches and tags in git-svn. It is now possible to use globs like 'a*e', or 'release_*'. This allows users to avoid long lines in config like: branches = branches/{release_20,release_21,release_22,...} In favor of: branches = branches/release_* [ew: amended commit message, minor formatting and style fixes] Signed-off-by: Victor Leschuk <vleschuk@accesssoftek.com> Signed-off-by: Eric Wong <normalperson@yhbt.net>
