The bzr tests are the only .t tests calling hghave (aside from the tests
testing hghave itself). This pattern is a one-off and prevents
desired refactors to how requirements checking is integrated into tests.
Use the convention used everywhere else.
Instead of opening the target bzr checkout as a single branch, we try to open
it as a repository. This has the following effects:
- All branches are now converted
- bzr branch names are preserved. Previously, the selected branch was always
converted as 'default'. Branches without a name or 'trunk' are mapped to
'default branch.
- Lightweight checkouts are no longer supported. Maybe they can be, I did not
try to fix that at all.
Implementation notes:
- This was a quick fix, I have no knowledge of bzr API besides browsing 2.0.3
sources.
- The fix was only tested on OSX against bzr 2.4.2.
- Tags discovery does not handle collisions. I have no idea how tags work in
bzr so maybe such collisions are not possible.
