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]

should be manually entered with a text-editor or using 'git config'.

Also note that only one asterisk is allowed per word. For example:

branches = branches/re*se:refs/remotes/project-a/branches/*

will match branches 'release', 'rese', 're123se', however

branches = branches/re*s*e:refs/remotes/project-a/branches/*

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