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.
