Recipe:

1. Save the following text as the test bookmark file

;;;; Emacs Bookmark Format Version 1;;;; -*- coding: utf-8-emacs;
mode: lisp-data -*-
;;; This format is meant to be slightly human-readable;
;;; nevertheless, you probably don't want to edit it.
;;; -*- End Of Bookmark File Format Version Stamp -*-
(("test" (filename . "/ssh:192.168.0.100:~/") (front-context-string)
 (rear-context-string . "g-style=literal\n") (position . 68)
 (last-modified 25595 64776 373828 978000)))

2. emacs -Q --eval '(setq bookmark-default-file xxx)' -f list-bookmarks

3. press d, then x.

However, the bookmark cannot be deleted because Emacs hangs or displays
tramp error message/popup window after several seconds.

Thank you for the recipe, I can reproduce the problem. It happens,
because in `bookmark--remove-fringe-mark' there is a call of
`expand-file-name', which blocks if a remote file is not reachable.

Could you pls check the appended patch? It fixes your recipe for me, and
shouldn't harm other use cases.

Best regards, Michael.

Thank you! I confirm it works.

BTW, I find binding non-essential to t fixes a similar problem caused
by abbreviate/expand-file-name on remote files:

1. save the following text to file A:

;;; -*- coding: utf-8; mode: lisp-data -*-
(("/ssh:192.168.0.100:~/a.txt" . 282))

2. emacs -Q --eval '(setq save-place-file <file A>)' -f save-place-mode

Thanks for the feedback.

Indeed. I've pushed the change for bookmark.el and saveplace.el to
master, closing the bug.

Best regards, Michael.
