Hi,

I’m skeptical since we have only one (or two?) use cases.  I think we
should weigh the added complexity, both in terms of implementation and
of semantic clarity, compared to reduced complexity elsewhere.  It seems
to me that the costs outweigh the benefits here.

Also, the empty search path entry has a special meaning.  For
EMACSLOADPATH, that entry doesn’t have to be last, one can choose to put
it in the middle of the search path (info "(emacs) General Variables").
The trailing separator is just a special case.

WDYT?

Thanks,
Ludo’.
