Ah, got it! It was just I thought I'd seen a file with its own section
which was also in the "innocent" section at the end. I've had a look for
this, and can't find it. So I must have been mistaken.

OK. This is obviously very important. The patch I posted here isn't up
to scratch for that. I'll need to improve it.

What I'll be doing is sorting the "no-autoloads" list so that it's in the
same order as the file entries. I can then loop through all the files,
testing in turn whether the file was a "no-autoload" or had its own
section, and take the appropriate action. That will mean never having to
search loaddefs.el for an entry, and not having to use `member' in the
"no-autoloads" list, since I will be stepping through both from start to
finish.
