Yep. It probably calls isatty() on the standard streams, which in the
case of the Windows C library (MSVCRT) returns false for pipes, which
Cygwin's pty emulation is based on.

It shouldn't be horrendously difficult, however, to add a switch for
forcing interactive mode to the mysql client. Python does have such a
switch. Perhaps you could raise this on the relevant mysql mailing
list?
