The *.slc files are bye-compiled versions of the corresponding *.sl files in
the packages jed-common and jed-extra.

Placing them alongside the sources is common practice and prevents
surprises when customizing the editor (using a custom jed-library-path,
using drop-in replacements from jed-extra or locally installed).

The same scheme is used by Python-2 packages: the generated *.pyc files are
stored alongside the *.py source under usr/lib/...

The byte-compiled filea are no more variable than the rest of the
package, as they are only generated/deleted when the package is
(de)installed or updated.
