Subject: [PATCH] patch-bac.canonifypath-4.

The attached patch reverts the IMAP canonification patch I reverted
a version ago (sorry for being so wishy-washy). This time I put in
some code to preserve IMAP URL passwords in the initial pass, so
people who like to use those sorts of URLs still can. That was the
only reason I had reverted the patch before.

(From Brendan Cully.)
