Using different code pages for console input (SetConsoleCP()) and console
output (SetConsoleOutputCP()) doesn't make much sense and may be hazardous
for native Windows programs.
Git uses UTF-8 internally, so it actually needs 'SetConsoleCP(CP_UTF8)'
rather than 'SetConsoleCP(GetACP())'. However, ReadFile() / ReadConsoleA()
are broken with CP_UTF8 (and thus any higher level APIs such as fgetc(),
getchar() etc.). Unicode-aware console input would have to be implemented
via mingw_* wrappers using ReadConsoleW(). As Git typically launches an
editor for anything more complex than ASCII-only, yes/no-style questions,
this is currently not a problem.
Drop 'SetConsoleCP()' from the git-wrapper, so that input and output code
pages stay in sync.
