Thanks.  I added implementation for MS-Windows.

The result is not 100% satisfactory, as one needs to press RET twice
to finish the input, and it looks like some garbage is left in the
input buffer, since the following (normal) input gets something
strange.  A workaround is to press C-z, which produces EOF, instead of
RET, when password entry is finished.

I also needed a change in minibuf.c to end the reading loop on CR, not
just a newline.  If this is bad news for Posix platforms, we can make
that code conditional on Windows.
