I feel sorry for wasting your time in this way.

And we want the user's .el and the corresponding .eln to override
the system-provided ones. So those (more precisely: their directories
should go first in their corresponding paths, right?

I must have expressed my thoughts too clumsily. I do agree with you
that the several paths are in order of descending preferences.

What I'm implying from that is that the place for the user's .eln
files should be more at the front of this path, so the .jit mechanism
should put them there, if they have to override the system-provided
ones.

Let's forget about those for now :-)
