You still didn't answer the question: how can cygwin know which
arguments are pathnames?  Finding a correct solution to this
problem is entirely non-trivial.  If you mean that cygwin should
treat everything that looks like it might be a pathname as a pathname,
then that is not a correct solution, and I think an incorrect
solution is going to cause more problems than it solves.
For example, consider the command `sed /usr/p /usr/p'.
In that command, the first argument is a sed command, meaning
"print all lines containing `usr'", while the second argument
is a file name.
