Surely any new option should come with a patch to invoke.texi to document
it?  I think documentation for any user-visible features should be
considered a necessary part of any patch, not an optional extra.  (I'd
also say the same of testcases - you must have tested the patch, so can at
least add a testcase to the testsuite as a sanity check to ensure that
no-one breaks the option by accident.)
