[cbm4linux-users] Possible crash if cbmformat or d64copy are called with unknown long options

[Spiro T. <cb...@tr...>]

Hello,

the attached patch fixes a possible crash if cbmformat or d64copy are
called with a long option which is not known. It seems that cbmcopy is
not affected by this bug "by accident".

In the declaration of the long_opts[], it was forgotten to mark the end
of the list with an entry which consists completely of zeroes (cf.
getopt_long(3): "The last element of the array has to be filled with
zeroes.")

Examples for this error:

Try

cbmformat --zzz
d64copy --zzz

Regards,
   Spiro.
