The fact that one's username can contain weird characters doesn't mean
a shell will expand it, though.  I (and someone else in an M::B RT
ticket) did some digging in some sources, and apparently expandable
usernames are something like

 m/\w[-\w]*/

That's what the M::B::Platform::Unix::_detildefy() method accepts now, in SVN.
