[issue12444] accept sets or collections for str.strip/lstrip/rstrip

[Peter Eisentraut]

New submission from Peter Eisentraut <peter_e at gmx.net>:

It appears to be a pretty common mistake to think that the argument of str.strip/lstrip/rstrip is a substring rather than a set of characters.  To allow a more clearer notation, it would be nice if these functions also accepted an argument other than a string, for example a set or any collection.  Then you could write, for example:

a.strip({'a', 'b', 'c'})

I suggest to either add support for sets specifically, or more generally anything that supports the "in" operator.

I can try to code it up if it sounds acceptable.
