Turns out there was an earlier patch, written by Matthew Grooms
<mgrooms at shrew.net>, that provided the same functionality,
and was submitted in PR 204901. While I don't remember seeing
the actual diff (I'd just commit it if I had), and the code looks
different, I do remember discussing this, and Matthew's analysis
of the problem was crucial for getting this done. The code also
works in a pretty much same way. Great minds think alike, I
guess :-)
(I should learn to check the PR database before writing code,
though. Sorry for that.)
