No changes, just simplify the code using wx2stc() a little.

Assign wx2stc() return value to a suitably const variable instead of using
ugly casts to get rid of constness.

Also use wxCharBuffer/char* explicitly inside explicit wxUSE_UNICODE checks,
using wxWX2MBbuf here doesn't gain us anything and just confuses the reader of
this code.
