paths: Add support for -q/--quiet
Suppresses output (resolved paths or "not found!") when searching a path,
similar to "grep -q".
Sample usage: hg paths -q foo || echo "there is no foo"
Just prints path names (instead of "name = result") when listing all path
definitions, like "hg bookmarks -q".
Sample usage: hg paths -q | while read i; do hg incoming "$i"; done
$ "$TESTDIR/hghave" inotify || exit 80
$ hg init
$ echo "[extensions]" > .hg/hgrc
$ echo "inotify=" >> .hg/hgrc
$ hg inserve -d --pid-file .hg/inotify.pid
$ echo a > a
$ hg ci -Aqm0
$ hg co -q null
$ hg co -q
$ hg st
$ cat a
a
$ kill `cat .hg/inotify.pid`
