No, now it's just canonicalizing as early as possible.  Preferably within the
object accessor rather than at the point of use.  So in the code below,
$full_url is already escaped/canonicalized.

In general this blob patch isn't going to make a lot of overall sense.  I'm
working with Jonathan to get it submitted in manageable pieces.

Good point.  More importantly, what was it trying to accomplish before and
does it need to be preserved?

"If the URL is svn OR its http and needs to be escaped... do something
special".  I don't really understand what the special stuff in the following
block is.  Anything that undef's the invocant (ie. $self) is probably broken.

a51cdb0c0420ee3bef26bbd1a9aa75e1d464e5b7 and
2a679c7a3148978a3f58f1c12100383638e744c5 shed some light.  2a679 looks like it
specifically holds off on escaping $full_url.  It would be very nice if that
was not necessary.  It would be helpful if the bug mentioned in 2a679 could be
reproduced to see if it still applies or can be dealt with in another way.
