Remove the sentence about only root being able to run watch(8). It
was never technically true (it's snp(4) that required root, not watch(8)), and after snp.c 1.64, isn't even effectively true, since who can run watch(8) depends on the permissions of the snp device(s). Sort options in SYNOPSIS and DESCRIPTION while I'm here.
