Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Hi, with current version of `bookmark-write-file' saving a big list of
bookmarks is very long:

More than 50s for 195 bookmarks.

That's because entire `bookmark-alist' is given to pp:

,----[ bookmark.el:bookmark-write-file ]
| (pp bookmark-alist (current-buffer))
`----

With this modification i made in bookmark+.el, for same 195 bookmarks,
it take only 1.24s:

,----[ bookmark+.el:bookmark-write-file ]
| (progn (insert "(")
|        (dolist (i  bookmark-alist) (pp i (current-buffer)))
|        (insert ")"))
`----

Little chunks of `bookmark-alist' are given one by one to pp and that is
faster.
