branch: feature/gnus-select
commit 88a19e4419be75aed430c7cb8fd084a1acf5f4ab
Author: Stefan Monnier <address@hidden>
Commit: Andrew G Cohen <address@hidden>

    * lisp/desktop.el: Make use some "new" functionality
    
    (desktop-files-not-to-save, desktop-clear):
    Use \` and \' when we don't intend to match newlines.
    (desktop-minor-mode-table): Remove auto-fill-function entry.
    (desktop-buffer-info): Use :minor-mode-function instead.
    (desktop--v2s): Use a closure rather than a backquoted lambda.
    (desktop-save): Set 'lexical-binding' in the saved file.
    Use 'utf-8-emacs' encoding rather than the old 'emacs-mule'.
    (desktop-read): Use 'default-value' to get the global part of a hook.
