For example, I have `delete-trailing-whitespace' in my
`before-save-hook', but for a particular buffer I wanted to save it
without removing the trailing whitespace, because trailing whitespace
was syntactically meaningful in that case (the buffer contained some
Markdown-like source code).

I searched the Internet for some solutions and what I ended up doing is
C-x C-q (to make the buffer read-only), C-x C-s, and C-x C-q to make the
buffer writable again (from
https://stackoverflow.com/questions/14913398/in-emacs-how-do-i-save-without-running-save-hooks).
It felt a bit like a "hack".
