[Python-Dev] Re: PEP 616 -- String methods to remove prefixes and suffixes

For clarity, I'll change

If ``s`` does not have ``pre`` as a prefix, an unchanged copy of ``s`` is returned.

to

If ``s`` does not have ``pre`` as a prefix, then ``s.cutprefix(pre)`` returns ``s`` or an unchanged copy of ``s``.

For consistency with the Specification section, I'll also change

s[len(pre):] if s.startswith(pre) else s

to

s[len(pre):] if s.startswith(pre) else s[:]

and similarly change the ``cutsuffix`` snippet.
