vim-patch:8.0.0243

Browse Source 
Problem:    When making a character lower case with tolower() changes the byte
            cound, it is not made lower case.
Solution:   Add strlow_save(). (Dominique Pelle, closes vim/vim#1406)

cc5b22b3bf

Join almost identical strup_save and strlow_save functions to one
Function.
