Fix help and documentation for inferior commands

Browse Source 
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.

-- a space separated list of inferior numbers -- can be used to limit
the display to just the requested inferiors.
