[PATCH] RelNotes: fsmonitor: add a pointer to man page and the word itself

[Yasushi SHOJI <yashi@atmark-techno.com>]

Add a pointer to git-update-index(1) and a bit more detail about
fsmonitor and watchman to help people following up the new feature.

Hi Ben and Junio,

Wouldn't it be nice to tell the world a bit more about "file system
monitor" we now support?  I think that "git status" and "watchman"
might not ring the bell for some, but adding a word "file system
monitor" may.

I know most of repos don't need fsmonitor but it's a cool feature to
have it. ;-)

WDYT?
