Subject: bug#52917: 29.0.50; pp-use-max-width=t can break bookmark-save
Date: Fri, 31 Dec 2021 17:18:25 +0100 (CET)

When the user option `pp-use-max-width' introduced in Emacs 29 is set to
t, `bookmark-save' can fail.  Following the backtrace points out the
problem lies in `pp', specifically `pp-emacs-lisp-code', which fails to printthe following bookmark record produced pdf-tools,

("Last read Peter Sykes"
(filename . "~/doc/uni/refb/A_guidebook_to_Mechanism_in_Organic_Chemistry_Peter_Sykes.pdf")
(position . 1)
(page . 263)
(slice)
(size . 4.367774566473988)
(origin 0.0 . 0.5892997639653816)
(handler . pdf-view-bookmark-jump-handler))

Let-binding `pp-use-max-width' to nil in `bookmark-save' should fix the
problem, I think.

Following is the backtrace produced when trying to save bookmarks (I hope it
doesn't get mangled),
