 + mingw: intercept isatty() to handle /dev/null as Git expects it

 We often decide if a session is interactive by checking if the
 standard I/O streams are connected to a TTY, but isatty() emulation
 on Windows incorrectly returned true if it is used on NUL (i.e. an
 equivalent to /dev/null). This has been fixed.

I'd like to suggest a reword: we did not use an isatty() emulation, but
Windows' own _isatty() function that simply has different semantics than
what Git expected. *Now* we have an isatty() emulation that wraps
_isatty() and emulates the behavior expected by Git.

Thanks,
Dscho
