Thanks for the report.  It seems that there is a minor bug in main.c.
The "optlist" string is set as follows:

        const char *optlist = "+F:f:v:W;bcCd::D::e:E:gh:i:l:L:nNo::Op::MPrStVY";

This contrasts with

        { "help",               no_argument,            NULL,   'h' },

There seems to be a stray colon after the "h" in optlist.  If that
is removed, the exit status will be zero in both cases.

The attached patch seems to fix the problem.

Regards,
Andy
