[PATCH 2/3] chcp: Return the active code page when called without arguments.

[Erich E. Hoover]

After doing some sleuthing on MSDN, chcp treats the input console code
page as the "active" code page (GetConsoleCP instead of GetACP).  This
will appease applications that expect chcp to return the "active"
console code page.

Best,
Erich
