From: Jeff Hostetler <jeffhost@xxxxxxxxxxxxx>
Add the "feature: fsmonitor--daemon" message to the output of
`git version --build-options`.
The builtin FSMonitor is only available on certain platforms and
even then only when certain Makefile flags are enabled, so print
a message in the verbose version output when it is available.
This can be used by test scripts for prereq testing. Granted, tests
could just try `git fsmonitor--daemon status` and look for a 128 exit
code or grep for a "not supported" message on stderr, but this is
rather obscure.
The main advantage is that the feature message will automatically
appear in bug reports and other support requests.
