bug#55863: 29.0.50; [PATCH] Avoid hanging chad of *Backtrace*

[dick]

So I set about replacing kill-buffer with bury-buffer, then demoting
the *Backtrace* buffer from debugger-mode to backtrace-mode, and
realized maybe kill-buffer is best.

The confusion is we're accustomed to "q" as a passive bury, when
in fact "q" in debugger-mode corresponds to the highly un-passive
"debugger-quit".  To emphasize that, perhaps "q" in debugger-mode
should be gated by an "Are you sure?" yes-or-no-p.

Toting around old *Backtrace* buffers is fraught.  As GNU is really a
preservationist society moonlighting as software developers, I expect I
am, as usual, in the minority and will bow out of this particular
discuz.
