[Message part 6 (text/plain, inline)]

I'll push this to emacs-30 when I get a bug number.  While such a
straightforward doc fix would normally be committed without a bug
report, after looking into the history of the code related to this piece
of documentation, I found it interesting and perhaps instructive enough
to share here (but not appropriate for the ChangeLog).

The user option `desktop-clear-preserve-buffers-regexp' was added in
April 2003 (in commit 4a2fce7a9fdff3ede6f945e19e13154042dcb471) and was
intended to replace the existing user option
`desktop-clear-preserve-buffers' (added in 1997 in commit
21f521c0db6b683a2407a02d8a1706df8c9a7baf).  The latter was consequently
made obsolete in September 2003 (in commit
c5b31c4d7923a82a2937877f891a5e67f7ea6511) and also at that time
`desktop-clear-preserve-buffers-regexp' was documented in the Emacs
manual.  However, in September 2004 `desktop-clear-preserve-buffers' was
unobsoleted (in commit 340db502fa63af19824db898fec3fd7c6ba5ce0c).  Then
in August 2005 `desktop-clear-preserve-buffers-regexp' was deleted
(without having been previously obsoleted) and its functionality was
incorporated into `desktop-clear-preserve-buffers', but the
corresponding documentation in the Emacs manual was not updated and has
remained unchanged since then (although that node of the manual was
substantially rewritten in January 2023 in reaction to bug#60600).
