Subject: Minor fix for a defcustom in savehist mode (patch included)

[Message part 1 (text/plain, inline)]

While customizing savehist mode through the emacs Custom interface, I
discovered that I could not set `savehist-autosave-interval' to nil
because the custom buffer only had an integer entry field for that
variable, although the docstring said that nil was a valid value. So I
edited the custom definition to allow choosing either nil or an integer,
instead of just an integer. I also added labels to the two choices to
make things clearer for the user. Here is the one-line diff (assuming
that it doesn't get too badly mangled in transit):

BEGIN DIFF

 (defcustom savehist-autosave-interval (* 5 60)
   "The interval between autosaves of minibuffer history.
 If set to nil, disables timer-based autosaving."
!   :type 'integer
   :group 'savehist)

 (defcustom savehist-mode-hook nil
--- 120,127 ----
 (defcustom savehist-autosave-interval (* 5 60)
   "The interval between autosaves of minibuffer history.
 If set to nil, disables timer-based autosaving."
!   :type '(choice (const :tag "Disabled" nil)
!                  (integer :tag "Seconds" 300))
   :group 'savehist)

 (defcustom savehist-mode-hook nil
END DIFF

Here is my attempt at manually writing a changelog entry:

BEGIN CHANGELOG
    2009-11-62  Ryan C. Thompson  <rct <at> thompsonclan.org>

            * savehist.el: Allow setting `savehist-autosave-interval'
              to nil in Custom.
END CHANGELOG

If it matters, you have my blessing to license this code however you please.

Please post your bugfix to Emacs maintainers so it gets incorporated
into the next release.  I no longer actively maintain savehist-mode.

Thank you.
