formatter: add helper to create a formatter optionally backed by file
To make things simple, openformatter() and maybereopen() have no support
for a plain object API. Callers must use the "with" statement.
Unlike cmdutil.makefileobj(), append mode ('ab') isn't supported by these
functions. This is because JSON output can't be simply concatenated. Perhaps
cmdutil.export() will have to build a {filename: [revs...]} map first and
write revs per file.
====================================
Testing head checking code: Case A-2
====================================
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 A: simple case involving a branch being superceeded by another.
TestCase 2: multi-changeset branch
.. old-state:
..
.. * 1 branch with 2 changesets
..
.. new-state:
..
.. * another 2-changeset branch succeeding the old one
..
.. expected-result:
..
.. * push allowed
