The system shell on w32 does not expand wildcards (or even split words),
so programs built for w32 must do any expansion themselves.  The various
Unix-on-Windows approaches typically try to do splitting/expansion before
calling main() so that the ported programs see what they would expect from
a Unix shell.

So it's likely that ruby is choosing to do the expansion itself (and then
doing who knows what with the other matches).  You might be able to fix it
by passing the argument with double quotes or so; it depends on the
details of the Unix emulation layer in use.
