Subject: Fix 4 bugs in lb

 1. Check if the command exists *and* is executable
 2. Quote ${command} in case it contains whitespace, which would break
    syntax in the test (though, because it uses Bash builtin "[[" instead
    of the normal "/usr/bin/[", Bash *usually* recovers from this safely.
 3. Go ahead and exit with an error if we print a fatal error message,
    don't keep running.
 4. Put "$@" in quotes; it preserves whitespace in the arguments (while
    still keeping separate arguments separate).
