All that is fine, but the question was about producing the eln file in
the first place.  The documentation and the information posted here
indicated it will be produced when the elc file is loaded.

That explicitly does not happen in those cases I enumerated above, and
in some other cases.

The backstory is I wanted to test something without putting it
load-path.
