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,...}

Changes from $gmane/283172:
* Not only prefixed globs are allowed now (one can put '*' in the middle of a word) - thus changed patch name
* Added tests for globs in the middle of a word

It is also possible to fetch a subset of branches or tags by using a
comma-separated list of names within braces. For example:
