Bug Description

This may simply be a usage problem (i.e., I don't know how to use this plugin), but I can't seem to branch (or clone) an hg repo with bzr-hg.

For example executing this:

$ bzr branch http://hg.barryp.org/py-amqplib-devel/ trunk

Results in this (snipped) output:

bzr: ERROR: Unknown bzrdir format: '<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US">
...
</html>

Here's my version info:

$ bzr version
Bazaar (bzr) 1.17dev
  Python interpreter: /usr/bin/python2.4 2.4.5
  Python standard library: /usr/lib/python2.4
  bzrlib: /usr/lib/python2.4/site-packages/bzrlib

$ hg --version

bzr-hg only works on local repositories atm

summary: - Latest bzr and bzr-hg don't seem to work
+ no support for remote repositories

Until remote repository support is available, might I suggest this short-term "fix"? :-)

There is now basic support for remote repositories.

This is caused by the fact that the remote web server returns a non-404 HTML page when we request .bzr/branch-format.

The attached trivial patch works around this problem, but it's not very elegant..

affects: bzr-hg → bzr

Not really elegant, but I'm not sure what a better workaround would be at the moment. Perhaps we can just handle UnknownFormatError like NotBranchError in the transport prober?

I think merging Jelmer's patch from #5, which assumes a multi-line format is garbage, along with a comment about why we're doing it, would be ok. But changing the general format detection to keep looking in the case it sees an UnknownFormat is probably better.
