+-genisoimage_completion
+     Match unrecognized option arguments which begin by a dash '-'
+     against the known genisoimage options, like program genisoimage
+     does unconditionally (and undocumentedly).  If the given argument
+     matches the beginning of exactly one genisoimage option, then it
+     gets replaced by that option.  Options which are genuine to mkisofs
+     or xorriso's mkisofs emulation are not matched that way.  Option
+     arguments which consist entirely of a leading dash and letters out
+     of "dDfJlNRrTUvz" are not matched but rather interpreted as usual,
+     i.e.  as multiple options with leading dash and each single letter.
+     If no genisoimage option is found or more than one are found, then
+     a SORRY message is issued and the argument stays as is.
+     To enable this mode by default, write the xorriso command
+     -genisoimage_completion on
+     into one of the xorriso start files.  See section FILES.

+Match unrecognized option arguments which begin by a dash '-' against the

+genisoimage does unconditionally (and undocumentedly). If the given argument
+matches the beginning of exactly one genisoimage option, then it gets replaced
+by that option. Options which are genuine to mkisofs or xorriso's mkisofs
+emulation are not matched that way.
+Option arguments which consist entirely of a leading dash and letters out of

+multiple options with leading dash and each single letter.
+If no genisoimage option is found or more than one are found, then a SORRY
