Re: [msysGit] [PATCH v3 08/14] daemon: use run-command api for async serving

fork() is only available on POSIX, so to support git-daemon
on Windows we have to use something else.

Instead we invent the flag --serve, which is a stripped down
version of --inetd-mode. We use start_command() to call
git-daemon with this flag appended to serve clients.
