Subject: Make `todo-toggle-item-highlighting' work on multiline items (bug#27133)
X-Git-Tag: emacs-26.0.90~521^2~236
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=ed222c502b1a0043a8bc606482a11516568a54b6;p=emacs.git

Make `todo-toggle-item-highlighting' work on multiline items (bug#27133)

* lisp/calendar/todo-mode.el (todo-hl-line-range): New named function,
replacing an anonymous function for the sake of `describe-variable'.
(todo-modes-set-2): Use it as buffer-local value of hl-line-range-function
and remove boundp test of this variable, so its value is available on
invoking `todo-toggle-item-highlighting'.
