Hey.  It got $0 right.

So I take it this "idiom" is only supposed to work in newer cygwin versions?

And I too am puzzled why someone would defeature a shell instead of letting it work with either
method.  I don't see it as a portability issue unless you think a significant number of users will
be porting their scripts from systems running cygwin to systems running atavistic variants of UNIX.
