Yes. (And the current code ignores it even when it is non-nil. Actually,
the current code ignores everything -- it simply tries the one single
file name it guesses is right and either finds it or errors out.)

OK, I think I get it, thank you very much for the explanation. Honestly,
this kind of loading seems pathologic to me -- it never crossed my mind
to load/require "path/file" instead of first adding "path" to
`load-path' and then `load'ing "file". What use does this have? Or
rather, is it necessary (I imagine people might be trying to use this as
a poor man's module system)?
In any case, I'm obviously still missing a lot (such as how the case
with symbols defined outside load-path is handled or how the Help cross
references come into play -- they still don't work even with my "fix");
I'll try to look at the code some more.
