That was my first version indeed.  Unfortunately:

Exactly.  So that 'if' was a way to shut up the compiler complaining
about the unused result of the ||-chain.  Perhaps not the best way to
do that, but I couldn't come up with any better.

I had a note about it attached to the commit, but then run
'format-patch' without '--notes'...  oh, well.
I guess I should have wrote that in the commit message to begin with,
shouldn't I?  Or in an in-code comment.
