The ChangeLog is somewhere, but as usual I forgot to commit it at the time
and now I'm working on another computer.  But trust me, it's not lost.

It's odd that such a change would fix/break some code.
After all `gensym' is more or less doing (make-symbol (concat "G"
(random))), so other than the symbol's name, nothing is changed.
And since the symbol is uninterned, its name is mostly irrelevant, unless
some code later on uses `symbol-name' or does a print+read without using
print-gensym.

Maybe we'll indeed have to revert to gensym here, but I'd like to first
better understand the problem.

Could you give us a recipe to reproduce the problem, and a backtrace
if applicable.  Of course, ideally the recipe should not use emacs-w3m,
but as a first step it would still help to see a recipe and a description of
the resulting problem.
