Yes, to be clear, I'm talking about a case where the Lisp files are in
source-directory, not where they don't exist at all.  If the Lisp files
are in source-directory and stay around there, then perhaps they don't
need to be copied to /usr/share.

But if we want to always copy them to /usr/share, that's fine, it's not
necessary to support skipping that.

My suggestion, then, is that we should allow customizing Emacs to prefer
jumping to source-directory over jumping to the installed copies of the
Lisp files.
