No need for usage() 

There are 2 arguments why -v and -h are broken:

	1) if you are running off git, -v will show the last stable
           release, effectively making this option useless.
           people running stable versions leave open an attack surface
           this way in case there are vulnerabilities found.
           99% of the people are also using package managers to keep
           their software up to date, instead of running $TOOL -v to
           check how old it is.
        2) -h is a sad excuse for not just looking at the manual page
           (man 1 slock). Given we accept a post_lock_command, we can't
           be as liberal and just intercept certain flags.

I changed the manpage to reflect this change.
