Libc's wcwidth(), while not perfect, is used by most programs.
Implementation compatibility is necessary to avoid problems with string
width calculation and proper cursor movement.
The original wcwidth implementation files:
* COPYING.Unicode
* src/konsole_wcwidth.cpp
* src/konsole_wcwidth.h
are not removed yet.
