Don't think it's worth it.

a) All trivial replacements are already done by this set and the other
patches I've posted.
b) AI does a better job of handling this anyway, since it's able to
properly analyse the context and spot cases of using a length parameter one
short when calling strncpy, or when code is improved by using sizeof() as
the length parameter.

What probably is needed in scripting though, is a checkpatch check for new
strncpy additions. Are you still working on that python replacement?
