Yes, the standard way is as for bug reports and patches
R's bugzilla:  https://bugs.r-project.org/

One needs an account there, see
https://www.r-project.org/bugs.html  for an explanation (and
more),
but you already got such an account, since about one year,
so do go ahead.

Please keep the patch *minimal*,
i.e., no  white-space only changes etc

Thank you in advance for trying to make R better !

With regards,
Martin
