Bug#977112: texlive-latex-extra: dinbrief package is broken with texlive 20201203

[Erich Schubert <erich@debian.org>]

Package: texlive-latex-extra
Version: 2020.20201129-1
Severity: normal

The dinbrief package (last updated upstream 2000?) is broken now (it 
worked before the recent uploads of 20201203):

! Undefined control sequence.

                                                  }\aftergroup \reset@color

The following workaround worked for me:

after \begin{document}, insert:
\makeatletter\let\default@color\current@color\makeatother


I don't know whether it is worth fixing this package upstream, or 
dropping it,
given that it seems to be dead upstream for 20 years now. I guess I will 
try to
switch to scrlttr2.
