I take the question back. It looks like there is no elegant way to *only* trim a string passed to split-string:

split-string string &optional separators omit-nulls trim

For that, "separators" should be a regex that doesn't match anything in the string since "nil" defaults to split-string-default-separators (instead of, for ex. leaving the string as is and only defaulting when the parameter is omitted).

There are a number of regex that fit the bill according to stackoverflow, like:

(split-string string "[*]" t trim-regex)

but it's not elegant.

It would have been much nicer to implement from the start a "nil" option that does that... So I guess improving string-trim in subr-x.el is still relevant... Or am I missing something?
