I chose not to test backend version on the grounds that getting an explicit
failure for an explicitly requested option would be preferable to it being
silently ignored. However if the user is trying to use the same scripts for
many versions then ignoring unsupported but unessential features may be

One of the cosmetic changes made in response to other reviewers was to
not reuse lockquery, instead to have a separate query buffer. You have
reversed that and eliminated lockquery too. Which seems better.

I'll remember that next time.

All the other -X options are flags and supported directly by the getopt
machinery. Adding a -X option with an argument would require parsing
the argument by hand including dealing with '=' or ' ' as the separator and
telling getopt you had eaten an extra argument. This seemed a bit too much
code for the value of supporting a deprecated format for a brand new option.

Finally, you changed the option value and case from 1 to case 2. getopt_long()
only returns the value argument when there is no flag to set, so 1 was unique
and could have been read as "the first no-short option with an argument".

Thanks for checking this in.

If simplicity worked, the world would be overrun with insects.
