This is crude, but it lets you use "tag:foo/bar/grill" as a repository, and it replaces the "tag:foo" with a matching entry in ~/.svnrc like this:

tag foo svn://gcc.gnu.org/svn/gcc/trunk/whatever

So, with a .svnrc like this:

tag trunk svn://gcc.gnu.org/svn/gcc/trunk tag 4.0 svn://gcc.gnu.org/svn/gcc/branches/gcc-4_0-branch

You could just "svn co tag:4.0/gcc/config/i386"

It probably screams for lots more prettying up, but at least I did something about it ;-)

If you want it shorter, I could rewrite this so that the tag name goes before the colon, like "4.0:gcc/config/i386"
