Many years ago I wanted to install a tiny fix to work around a difference
between cmd.exe and 4DOS/4NT (a proprietary command shell for Windows), and
was told not to. IIRC, it wasn't even a change to bat-mode, but to one of
the .bat scripts used back then to build Emacs on Windows. Something
similar happened with CVS support vs CVSNT (it was a question of adding a
non-standard parameter that CVSNT required to be silent).
