The attached patch adds a feature to bookmark.el to colorize a bookmark's line, making it easily observable. The idea was adopted from package bm.el, available on MELPA. I was able to test this on Emacs 27, but there seem to have been some changes in snapshot to make it difficult to use that version of bookmark.el on my Emacs 27, so please verify that I performed the migration properly. OFF-TOPIC, but related: I've posted a pull-request to package bm.el adding to it a feature to make context-based suggestions for default bookmark annotations[1]. If Emacs wants that for package bookmark.el it should be possible to submit a parallel patch.
