You could use the same rules as skip-chars-forward.

I looked at skip-chars-forward before opening this bug but found it
complicate things by introducing new rules.

Which one?
IMO you may use skip-chars... internally, which is fast and reliable.

In strip-string the idea is to have a default covering 90% of the use

(strip-string s)        ; strip both
(strip-string s nil "") ; strip leading
(strip-string s "")     ; strip trailing

Suggest keeping either boolean for not, resp. default,
or a string containing chars overriding the default.

while this is obsolet meanwhile:



Refer users to regexp as in (info "(elisp)Regexp Special") for the
remaining 10% use cases.
