patchbomb: always use message-id of first patch for series-id This currently has the side effect that the 0 of N message has no series-id. This won't matter for Mercurial's own use, but may be undesirable for other projects depending on their workflow. The way the header is inserted is intentionally a little funny to make the test expectation diff easier to review.

test-patchbomb: normalize glob lines and record their construction This makes it significantly less painful to use --interactive on run-tests, as you can now use the recorded regular expression substitutions to fix up the glob lines and produce zero diffs. This also tightens the expectations of a few of the lines for the MIME boundaries - it just seemed like the thing to do while in here and causing some changes.

patchbomb: includes a unique series ID in email header Now that we have patch index and series size information, having a unique series identifier will helps tool to glue all email back together without any additional logic.

color: add parenthesis to help readability Took me a multiple attempts until my mind eventually stop reading: auto = coloropt = 'auto' And properly reads: auto = colorpopt == 'auto' So we add parenthesis to clarify.

status: document the content of the returned tuple in the docstring The ``status`` function returns a lot of information. We document it.

resolve: fix grammar of no matching files message
