I’ve pushed it to master.

I don’t have any documentation, but I did add a bit more information
to the comment.

Simply put, the system sometimes reports the fn key being pressed at
times when you wouldn’t expect it to, but only when ‘function’ keys
like <F1>, <tab> or <left arrow> are being used.

It also reports the fn key being pressed when you’re using it to turn
something like <left arrow> into <home>. We clearly don’t want that.
(i.e. fn‐<left> gives fn‐<home> instead of just <home>.)
