nethack --version:dump

Browse Source 
Add the 'dump' argument to the existing '--version' command-line
option to display the magic numbers used when validating save and
bones files for compatibility.

Nothing exciting, just a line of 5 hex values.  I was going to also
list the values for however many save and bones files are specified
on the command line but it seems to need more effort than I care to
expend.  And I hadn't made up my mind whether that should be done by
nethack, recover, or some new standalone program.  [Single line of
relatively raw output is so that they could be compared more easily.]

nethack --version:bad-argument was writing a message to stdout and
then starting play--which immediately overwrites stdout.  Have it
quit instead.  Player wasn't trying to start a game and quitting is
what it does with --version:good-argument.
