inotify: add a inotify.pidfile configuration possibility This will mainly help us in our tests to log pids of inotify servers started implicitely, to make sure that unkilled inotify daemons do not clutter the output of unrelated tests. Also desactivate the workaround introduced in 951ec6c7d703

cmdutil.service: do not _exit(0) in the parent process The fact that a parent process spawns a daemon does not necessarily means that it is the only think it has to do. This was forcing since 7c01599dd340 inotify processes launched implicitely to exit prematurely: when no inotify server was running, "hg st" for example would only launch a inotify server, _exit(0) and thus would not return file statuses. This changeset adds a test for implicitely launched inotify processes. Change to output of test-inotify-1208 is correct: it reflects the normal error message of "hg st" when not dying during "hg inserve" daemon creation.

commands, dates: use real lists instead of literal blocks

commands: use field lists instead of literal blocks in docstrings The literal blocks were mis-used for alignment, but this of course changes the font of the entire block to a fixed width font in the HTML version. Using a proper list solves this.
