minor sysutils question under win32

Пётр Косаревский
Why does sysutils use CharUpperBuff() user32.dll function instead of CharUpper(): it does not check the return value?

(last 2.1.x SVN)

By the way: (from MSDN regarding CharUpper()) "Return value...There is no indication of success or failure. Failure is rare."
