git-svn and branches with spaces

As others have noticed, git-svn can't handle branches with spaces.

Turns out that there is a possible workaround: thiago's 
svn-all-fast-export tool is super super configurable, allowing you to work 
around evil branch names by modifying your matching rules.

http://repo.or.cz/w/svn-all-fast-export.git

I made rules like this:

match /branches/crazy branch with spaces/
   repository myproject
   branch crazy_branch_with_spaces
end match

match /branches/([^/]+)/
   repository myproject
   branch \1
end match

Since the rules apply in order, the evil branch name matched before the 
catch-all matcher, fixing my problem.

And it doesn't hurt that svn-all-fast-export is at least an order of 
magnitude faster than git-svn clone...  If you find that git-svn is too 
slow, I strongly recommend svn-all-fast-export.git for performance alone!
