patch 8.0.0252: not properly recognizing word characters between 128 and 255

Browse Source 
Problem:    Characters below 256 that are not one byte are not always
            recognized as word characters.
Solution:   Make vim_iswordc() and vim_iswordp() work the same way. Add a test
            for this. (Ozaki Kiichi)
