inhibit: make rebase see obsolescence even for visible nodes
Rebase changed recently to take advantage of obsolescence markers to reduce
the number of conflicts to resolve. Inhibit users were unable to leverage this
new feature because none of their visible nodes could be obsolete. This patch
makes the nodes that would be obsolete without inhibit, actually obsolete for
the duration of the rebase to take advantage of the feature mentioned before.

inhibit: remove unused bookmark operation wrapping
Before this patch, inhibit was wrapping bookmarks.write and
bookmarks.recordchange. Since all the usage of bookmarks.write are not replaced
by bookmarks.recordchange all bookmarks operation happen in a transaction.
Inhibit already wraps the transaction mechanism to make sure that no revision
can end up being obsolete and visible. This makes the wrapping of
bookmarks.write superfluous.
Wrapping bookmarks.recordchange was wrong in the first place and redundant with
wrapping transactions.

inhibit: update test with new behavior from core
The recent changes in core (to make sure that all bookmarks write are done at
the end of a transaction) changed the behavior of inhibit. When one rebases
a set of hidden revs somewhere, the hidden revs become visible at the end of
the rebase. Both the previous behavior and new behavior seems acceptable but
the tests have to be changed subsequently. This patch modifies one of the test
for inhibit when the case mentioned above happens. We prune the revs inhibited
by the rebase to make the change minimal.

sense) and throws an error instead of crashing if the command is malformed.

directaccess: fix case of shortened hash containing only digits
For directaccess, there are four cases for what looks like short hashes made
of digits only:
1 | the hash is a revision number and not a short hash for another revision:
we don't change the visibility
2 | the hash is a revision number and a short hash for another revision:
we don't change the visibility

we don't change the visibility

_inhibitmarkers: turn the result from generator into a list
A generator object is always True, we have to turn it into a list in order to be

repository where transaction are expensive (hooks, cache invalidation, etc).
Writing this file less often have a minor effect on test where a stripped
changeset does not get removed from the obsinhibit file is still inhibited when
unbundled back. I think this is fine and I'm moving forward.

evolve: be more complete about copying extra from old revisions
For 'hg evolve' we want to copy all extra-level metadata except for
branch. This keeps the experimental topics extension from getting
obliterated by evolve runs.
Many hashes in tests changed due to some extra data coming along for
the ride in various places, but no functionality that was tested. It's
plausible that this copies too much metadata - maybe we should be
dropping rebase_src or convert_revision as well. Right now no tools do
that, so I'm biasing towards preserving everything except branch when
copying metadata for now.

evolve: remove unused warning message in _solvedivergent
Before this patch, we were checking for a case where a divergent changeset could
be public and printing a warning in that case. When we compute the divergent set
in the obsolete module we explicitely look for not public() changesets.
This patch removes this unused warning.

fold: avoid using x:y in the help
Suggesting "x:y" is a bad idea because x:y is a very deceptive revset.

evolve: improve the help of the fold command
The help of the fold command needed a little rework. This patch makes it a
little less verbose and adds an example. It also highlights a little more the
importance of the --exact flag.
