Ouch :(

ignore-paths is only for paths that get converted into part of the git tree

It's unfortunate, but there's not yet an exclude/ignore directive when globbing. You'll have to change your $GIT_CONFIG to only have a list of branches you want, something like this:

[svn-remote "svn"]
	url = svn://svn.mydomain.com
	fetch = path/to/repo/HEAD/root:refs/remotes/svn/trunk

	; have one "fetch" line for every branch except the one you want
	fetch = path/to/repo/BRANCHES/a/root:refs/remotes/svn/a
	fetch = path/to/repo/BRANCHES/b/root:refs/remotes/svn/b
	fetch = path/to/repo/BRANCHES/c/root:refs/remotes/svn/c

	; you can do the same for tags if you have the same problem
	tags = path/to/repo/TAGS/*/root:refs/remotes/svn/tags/*

But you shouldn't have to worry about having "fetch" entries for stale/old branches/tags you've already imported.
