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: 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.
