Yes, sorry, I have only looked at the line length because it came up as
a blocker.

As far as the file names, this appears stable, but the place in the tree
would move as part of this proposed integration, to be in
lisp/which-key.el rather than at the root as is the case for the ELPA
version.  Is this a problem and how was it resolved with other moves
from ELPA to core?

Upon inspection, the earlier historical commits do not generally conform to the
Changelog format.
How to investigate any issues for authors.el?  Is there a function try
and run?
