argument.  Use 'format-prompt'.  (Bug#56436)

Remove obscure, obsolete code from do_switch_frame

This is relevant for bug #56305, and might solve that bug.  The code being

workaround for switching frames, before the command 'other-frame' had been
written.  Nowadays, that code has harmful effects, causing frames' focus to be
redirected at random, sometimes back to the frame itself.

* lisp/net/net-utils.el (run-dig): Redefine in terms of `dig' and make
obsolete.  (Bug#56432).
(dig-program): Delete duplicate defcustom; it is also in dig.el.

* lisp/net/dig.el (dig-program-options): ...to here.
(dig-invoke): Respect 'dig-program-options'.
(dig): Prompt for DNS server when given double prefix argument.

Fix undo of changes in cloned indirect buffers

* lisp/simple.el (primitive-undo): If the visited-modtime of the
indirect buffer's file is bogus, use the modtime of the file
visited by its base buffer.

* src/undo.c (record_first_change): Call
'buffer_visited_file_modtime' with the correct buffer, instead of
always calling 'Fvisited_file_modtime', which returns possibly
bogus values for indirect buffers.

error for indirect buffers.
