Merge lp:~doxxx/bzr/534787-pull-lp-in-config into lp:bzr

[Gordon Tyler]

(doxxx) Fixed 'bzr pull' when lp: URL explicitly defined in locations.conf or branch.conf.

This fixes bug 534787 by fixing how get_transport tests whether a base path is actually a URL in its convert_path_to_url function.

It depends on lp:~doxxx/bzr/urlutils-lp-support for fixes in bzrlib.urlutils to handle lp: URLs.

[Martin Pool (mbp)]

That looks pretty nice. (Yet to review the other patch.)

Looks good. Only one tweak:

This NEWS entry should include the bug number. I'll fix that and land it (as
the prerequisite branch is now approved).

Thanks!

review: Needs Fixing

[Gordon Tyler (doxxx)]

Sorry, looks like I left a debugging change in, that should be assertFalse.
