Thanks for confirming that I might not be missing anything.

Maybe Emacs Dev would consider putting this in line with other at-point
functions.

How about deprecating `variable-at-point' and defining a new function
`var-at-point' that DTRT?

(I'm still curious how `variable-at-point' ever got to be defined that way. I
still do wonder if there wasn't perhaps a good reason at the time. I cannot
imagine one, but I've been surprised before.)
