Version 17.3.15 of web-mode.el uses a macro called save-mark-and-excursion.
The file is marked with
;; Package-Requires: ((emacs "23.1"))
However, that macro is not available in emacs 24.3.1, which I'm using on an old machine. The emacs package manager installs this new version of web-mode, but the package fails to work, giving an error about save-mark-and-excursion when you try to activate web-mode while visiting a file.
