Details:

Enter a minor mode in a REPL buffer, such as paredit-mode, evaluate something
that signals an error, and see that all the paredit bindings are gone when you
return to the REPL after the `Start debugger?' question.  This is because
MAYBE-SWITCH-MODES! replaces the command table list of the REPL buffer
*completely* with the command table list of the new mode, rather than
replacing only the command tables of the old mode with those of the new
mode.

Is it guaranteed that the list of a mode's command tables is always a tail of
any buffer in that mode?  If so, then the fix is simple: replace only that
tail, not the whole list, with the new mode's command tables.
