Granted, but that belongs to the "do what's needed to reproduce the
bug" part of my workflow. I don't see how it's relevant to the
discussion of *excessive* changes to the -Q environment.

I think that Customize already provides some function for listing
variables that are not at their default values, both Customized and
"rogue" values. Its output could be added to the bug-reporter's
buffer (maybe it's already there in Emacs, but XEmacs doesn't do that
yet). Perhaps it should be glossed with a comment that only
defcustoms can be listed this way.

OK.

I'm not sure I understand. Isn't that just a symptom of a poor
report, ie, omitting necessary preparation for reproducing the
behavior from the recipe? AIUI Lars' code is *not* going to suffer
from the problem you describe: only *necessary* changes to the -Q
environment will be made, and it's the reporter's responsibility, as
usual, to describe them accurately. I'll let Lars speak to the
details, though.

Sure.
