There's an interesting question here. We generally require that
arguments passed to our functions be valid, and if they aren't we tend
to die quickly and brutally. For example, if you pass non-cannonical
paths to a svn function you're likely to hit an assert rather quickly.
Are URLs like this considered valid or not?
