Please could you indicate me command-line tools where short-option
with optional-argument is possible.
Because if there is one, I could have inspiration to know how it
resolves the ambiguity.

The parser is not inconsistent with the rest of the world.  Or please
indicate with concrete examples what is wrong.

The issue is that Guix uses a bad practise: option with
optional-argument with both short and long name.  It is a mistake to
provide the short-name for such case.


Thank you for the report.  Now all this is clearer for me and I do not
think it is a fixable bug.

All the best,
simon
