changeset 4478:b2b55acbacdd

Add support for url#id syntax

This allows you to do:

 hg clone http://server/repo#stable

which is equivalent to:

 hg clone -r stable http://server/repo

Future incoming, outgoing, and push commands will default to using
this id because it's recorded in the default path.

Other commands that accept URLs (push, pull, bundle, incoming, and
outgoing) also accept this syntax.
