Hi,
in his review of the next patch of this series, Honza pointed out that
the path did not include documentation of a parameter it was adding.
When I set out to correct this I found out I had already been guilty
of not adding documentation of four other parameters before.
I'd like to correct this by this separate patch which I'd like to
propose also for 4.9 because it is missing there as well. Checked by
running make info. OK for both branches?
Thanks,
Martin
