Subject: Rewrite `b/*scratch*' function in init file
X-Git-Url: https://git.shemshak.org/~bandali/configs/commitdiff_plain/272a75dc74b1d02748472d5014be26aab7c060be?ds=inline;hp=78d731e133fcef8464acb1d0eb8a51864d0189cd

Rewrite `b/*scratch*' function in init file

* .emacs.d/init.el (b/*scratch*): Rewrite to use the new
`get-scratch-buffer-create' function in emacs.git master branch if
available, otherwise use the old `startup--get-buffer-create-scratch'.
