Hello Guix!

These three commits extend our search-path-specification record with a
new field, that can be used to produce a trailing separator, which can
be useful at least with Emacs (I can think of at least another place
where it could be used: the INFOPATH variable).

It was motivated to allow defining the Emacs search path in a more
robust way.

Thanks!

Maxim
