Summary:                    use grep -q instead of grep -s
Description: 
With bash 4.2 patchlevel 5, lin xproto gives error:

/var/lib/lunar/functions/misc.lunar: line 35: [: /usr/lib: unary operator
expected

The fix is to change the s to a q on line 35 (in "grep -s").

---------------------------------------------------------------------- 
reading man grep:

       -q, --quiet, --silent
              Quiet; do not write anything to standard output.  Exit
immediately with zero status if any match is found, even if  an  error 
was
              detected.  Also see the -s or --no-messages option.  (-q is
specified by POSIX.)

       -s, --no-messages
              Suppress  error  messages about nonexistent or unreadable
files.  Portability note: unlike GNU grep, 7th Edition Unix grep did not
              conform to POSIX, because it lacked -q and its -s option
behaved like GNU grep's -q option.  USG-style grep also lacked -q but its
              -s option behaved like GNU grep.  Portable shell scripts
should avoid both -q and -s and should redirect standard and error output
              to /dev/null instead.  (-s is specified by POSIX.)

we should propably avoid -q and -s and use redirection instead and change
all occurrences of grep -s and grep -q wherever they are (I guess it
concerns more than just misc.lunar).
