tests: add test of committing with conflicts but no changes in wdir I'm about to change the behavior slightly here, so let's have a test that shows that. Differential Revision: https://phab.mercurial-scm.org/D8194

transaction: clarify the logic around pre-finalize/post-finalize I am taking a bit more verbose route, but I find it easier to follow for people who (re)discover the code. (This is a gratuitous cleanup I did while looking at something else.) Differential Revision: https://phab.mercurial-scm.org/D8176

transaction: move constant to upper case These constant are internal to the module and can be safely renamed. Having them upper case help to clarify their "constant" status. (This is a gratuitous cleanup I did while looking at something else.) Differential Revision: https://phab.mercurial-scm.org/D8175

tests: handle In-Reply-To headers for line wrapping Python 3 tends to insert a newline for both Message-ID and In-Reply-To headers, so unwrap both. Just check the wrapped line format explicitly without regular expression. Differential Revision: https://phab.mercurial-scm.org/D8171

remotefilelog: add 'changelog' arg to shallowcg1packer.generate (issue6269) This cause traceback on widening using narrow extension when remotefilelog is enabled. Differential Revision: https://phab.mercurial-scm.org/D8134

remotefilelog-test: glob some flaky output line This is similar to ee0959e7d435. The affected line is flaky underload, yet the final result is correct. The command involves background pre-check of output, these are not stable probably because they run in parallel in multiple process. If it become useful to start testing precise internal details of the, they will have to be tested in a more appropriate framework than `.t` tests.

branch: make --force work even when specifying revs The `hg branch` command accepts a `--force` parameter that allows to "set branch name even if it shadows an existing branch". However, before this patch, that didn’t work when specifying revs with `-r`.
