According to Git's logs, w32-scroll-lock-modifier keyboard support was
apparently originally contributed by Geoff Voelker in 1999 (he has not
been active since that year) and subsequently maintained and documented
by you (last documentation changes in 2016).  For better or worse, that
probably makes you by far the best candidate for documenting (and/or
possibly even for fixing) the interactions of w32-scroll-lock-modifier
with default activations of the Scroll Lock keybindings on non-Windows
systems.
