RE: Updating from Emacs 23.3.1 to 25.3

Patrica, that is the best answer I've gotten yet. I'll  let you know
privately how it works. No use cluttering up the List.

Congratulations, my combined emacs config files have 1644 lines of actual
not-commented-out code.  (I should REALLY clean them up, but hey, they do
work.) They've been evolving since maybe 1990... I didn't think to capture
my first set of emacs config files which I started ~1986.

SO, when stuff breaks for whatever reason, here is what I do:

If the break is non-obvious, I just do divide-and-conquer to figure out what
isn't working in my .emacs or other setup files.

Comment out the bottom half of your .emacs (roughly; obviously you don't
break code to do this.)  I generally comment it with something like
";;PJH;;" using "string rectangle" so it's easy to strip out again.

Does that work? Yes? Great!  Drop a comment line at the top of the commented
section:
;;PJH works to here <2017-10-10 Tue>

Strip the comments from the top half of the commented section.  Restart
emacs.

Doesn't work? Great! The problem is in the chunk you just uncommented.
Comment out half of it.  Restart emacs.

Lather, rinse, repeat.

Oh, and if you're not sure if a particular config file is getting read or
not, go put an obvious error in it. Or add a line that will do something
clear and obvious.  (I call this, "If you can't fix it, break it worse.")

And as for directories moving around, below is a chunk from a historic
.emacs file of mine; note the commented-out code. 

I had this thing shared with a Windows virtual machine, and running OK on
both the Ubuntu host and OSCAR, the Windows virtual machine, which had my
elisp directory mounted as z:

Oh, and then I did some fun stuff with guix, but IMO it's not ready for
prime time yet, so the directory structures from that are commented out too.

I do go for pragmatic over nice...
