Yes, `string-trim' in in subr-x does it!

How are you supposed to find it tho?

Now I asked here. It isn't a bad way. But if we
exclude that as well as greping the web, I mean.

Because what I did was using `apropos'.
The reason it found the ERC stuff and not the
subr-x is because I had ERC loaded as my
IRC client, and subr-x wasn't even loaded!

Here is another example:

    (defun buffer-names ()
      "Get a list of all `buffer-name's."
      (mapcar #'buffer-name (buffer-list)) )

If I write two or more packs that both/all use
it, where do I put it? I don't want to put the
same thing in every one. But I don't want to
require it either because the packs are
one-file and I don't want to have the user have
to install yet another package to use them.
Especially since it would amount to countless
such packages... Perhaps I should put all into
one helper-pack and have just one (require
'mannys-utils) in all the rest!
