Actually, dealing with -c is the main reason why cmdproxy was
originally written. From the commentary near the beginning of
cmdproxy.c:
The main function is simply to process the "-c string" option in the
way /bin/sh does, since the standard Windows command shells use the
convention that everything after "/c" (the Windows equivalent of
"-c") is the input string.
So this is not a bug, it's a feature meant to avoid ugly
system-dependent code anywhere where a shell command is invoked by
Emacs.
