Yes, that is what I meant.

Well, hence I wrote "option for _arguments" for those commands, that use
GNU getopt.

No, it does not complete "corect" canditates. It completes totally wrong
set - options instead of arguments (files in case of diff). And this
change was introduced a couple of weeks ago ... and nobody has ever
complained before.
I think, old behaviour is "the least evil" case because it applies in
most cases. Apart from GNU getopt, there are commands that may intemix
options and arguments (with semantic - "this option applies to following
arguments" - do not have example ready) - but these are really special
cases and should be treated as such.
