cal: improve the help text and man page 

* misc-utils/cal.c: Add a little doc string, and mention that the
  current month is implicit if not specified.  Also remove mention
  of "current" from two option descriptions as a specific date may
  have been specified.
* misc-utils/cal.1: Likewise.

[kzak@redhat.com: - use fputs and USAGE_SEPARATOR]
