BTW, Here's a tip regarding trailing whitespace:

A simple way to remove all trailing whitespace is this:

 1. Enter picture mode:  M-x picture-mode
 2. Exit picture mode:   C-c C-c

The only side effect of this is that all trailing whitespace is removed.

I discovered this odd (and undocumented?) "feature" by accident about 20
years ago. So, it has been around since about version 18 of GNU Emacs -
perhaps it's even older.
