Subject: [PATCH] cal: display_help() tweak (#583)

* Example scenario: I type "perl cal -r", expecting it to work like it does on NetBSD
* I get a message that -r is invalid. Ok
* I get a message that cal is part of perl power tools; I don't care, I just want to see the valid options
* Remove the introductory text from display_help() and prefix the usage string with "usage: "
* The distribution info is still available at the bottom of the manual (perl perldoc cal)
