evolve: add pre-check logic for content-divergence in rewriteutil.precheck()
For now, pre-check will abort if rewriting a rev create divergence (and
config experimental.evolution.allowdivergence is not set to True).
But this behaviour can be improved where instead of abort maybe we
can confirm the user to either proceed with divergence or some other
options depends on what command user is running.
Changes in test file are used to overrides the pre-check for testing
purpose (using experimental.evolution.allowdivergence=yes).
====================================
Testing head checking code: Case C-3
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category C: case were the branch is only partially obsoleted
TestCase 3: 2 changeset branch, only the head is pruned
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is pruned
.. * 1 new unrelated branch
..
.. expected-result:
..
.. * push denied
