pgtk copyright headers

pgtk copyright headers

[Po Lu]

The files in the PGTK port have nonsensical dates in their copyright
headers.

Before update-copyright is run tomorrow (happy new year, by the way), I
think it would be appropriate to fix those dates:

  - pgtkterm.c, pgtkfns.c, and pgtkim.c say they are copyright 1989 to
    2020, while (judging by the VCS history) they should say 2017-2021.

  - pgtkgui.h and pgtkterm.h say they are copyright 2008-2020; they
    should also say 2017-2021.

  - pgtkmenu.c says it is copyright 2019-2020, while it should say
    2019-2021 instead.

  - pgtkselect.c says it is copyright 1993 to 2020, while it should say
    2017-2021.

Is it okay for me to make the necessary corrections now, or are there
some legal issues that have to be taken care of first?

Thanks in advance.

That's probably because those files started as copies of other files
in the Emacs tree.

The years need to be extended to cover 2021, but I would not remove
earlier years, because I'm quite sure a lot of that code was copied
verbatim from other Emacs source files.

The VCS dates have nothing to do with this, because the VCS doesn't
track simple copies of code fragments from one file to another.

No issues; please go ahead and fix this blunder.

Thanks.

Thanks, will do.
