[ You quoted a lot of text, so I'm not completely sure, but `C-s` seemed
to indicate that you were referring to just those above three lines
I kept. ]
I can't remember off-hand. Actually, I have a vague recollection that
the problems turned out having some other origin. So indeed we should
byte-compile the resulting file.

I don't know what this means.

I'm surprised a single call to `nconc` would be noticeably faster than
a hundred calls to `add-to-list`. I mean, obviously it's a lot faster,
but unless you do that in a loop (which is not the case here),
I wouldn't expect the difference to be measurable.
