Ughhh. Finally, after reading many, many info pages and running a dozen
or so google searches and reading four or five that many web pages over
the past couple days, I found what I was after... mapconcat. Still then
it took a bit of reading error messages and playing around with syntax,
but it's working. All that for one line of code!
I've programmed in a lot of languages over the decades, but elisp
definitely has the steepest learning curve... prolly cuz it's so
hodge-podgey. Well, this isn't a discussion I have time for. I'm just
sayin', if not for emacs, elisp would be gone... and it might be gone
anyway in a generation or two. I'll leave it to those who know the
language better than I to if/how to prevent that happening.
