    Don't consider colons to be paragraphs starting chars in strings

    * lisp/emacs-lisp/lisp-mode.el (lisp-fill-paragraph): Don't
    consider colons to start paragraphs in (doc) strings
    (bug#7751).

breaks filling doc-strings of defcustoms.  As an example consider the
defcustom of ‘window-min-height’ in window.el:


(defcustom window-min-height 4
  "The minimum total height, in lines, of any window.
The value has to accommodate one text line, a mode and header
line, a horizontal scroll bar and a bottom divider, if present.
A value less than `window-safe-min-height' is ignored.  The value
of this variable is honored when windows are resized or split.

Applications should never rebind this variable.  To resize a
window to a height less than the one specified here, an
application should instead call `window-resize' with a non-nil
IGNORE argument.  In order to have `split-window' make a window
shorter, explicitly specify the SIZE argument of that function."
  :type 'integer
  :version "24.1"
  :group 'windows)


Put point at the beginning of the last line of the doc-string and do

M-: (fill-paragraph)

This gets me here


(defcustom window-min-height 4
  "The minimum total height, in lines, of any window.
The value has to accommodate one text line, a mode and header
line, a horizontal scroll bar and a bottom divider, if present.
A value less than `window-safe-min-height' is ignored.  The value

:type 'integer :version "24.1" :group 'windows)

Okay, pushed to emacs-26 as a012ec766c9d9bac0a56e814589a4b3b93311c28.

Thanks for the tip, but I likely won't get to it soon. I think this
should be merged to master in the meantime.
