bug#13553: 24.3.50; incorrect usage of IS_DIRECTORY_SEP

[Shigeru Fukaya]

One more, please.

CharNextExA/CharPrevExA work based on dynamically specified codepage.

And, _mbspbrk/_mbslwr are also used in w32.c.  They work based on MS
Window's locale setting.

Isn't it inconsistent?  _mbsinc/_mbsdec would simply be sufficient?
(Besides, I don't know well, _mbslwr seems to me lower latin
characters' case on some locale.  Is it true, or intended behavior?)

Thank you,
Shigeru
