Bug?!?!  The real bug is this thread.  I consider the translation of \r,
\t, \n, etc. as a specifically stated feature found in all common
unices.  Now, if we're discussing operation from the cmd.exe/command.com
shells, and since Cygwin is aware of that fact, Cygwin could double the
'\' characters it finds in the command line while setting the argv array
before spawning the program to execute.  This would prevent this natural
translation.  AFAIK, it may already try to do this and is truly a bug in
Cygwin if it doesn't; but, this may be an unimplemented feature.
