Hello Eric and all,


Thanks for the quick and detailed review.
I've amended all the issues you mentioned.

These are of course Bernhard's improvements,
I just did the testing (and some minor things).

I've used your phrasing, and also separated "nohup" from the rest
of the programs, as it does not accept --help/--version anywhere,
just as first arguments.

Attached updated patches, with tests.

 P.S.
There is at least one change in behavior, not sure if this is
bad enough to be a regression or doesn't really matter:

  $ yes-OLD me -- --help | head -n1
  me -- --help

  $ yes-NEW me -- --help | head -n1
  me --help
