Fix help and documentation for inferior commands 

This changes inferior.c to add Usage lines for all commands, and to
change how "metasyntactic variables" are written to conform to GNU
style.

While doing this I noticed that the manual doesn't document the
argument to "info inferiors", so I've added that as well.

the display to just the requested inferiors.
