Try it the other way around.  You'll get the same result.

It has nothing to do with cygwin opening it first.  It has
to do with cmd not handling a "\\network\share" style address.

MS was too lazy to deal with command.com's "1-CurDir / drive"
scenario that is embedded in the Win32 interface.  If you cd to
//host/<currentdir>, //host isn't a drive letter.

So what happens when the user uses an absolute path?  "/tmp"...
where is that /tmp?   Ends up at the root of each drive, but on
a UNC-based-net-connection?  Undefined.  So cmd.exe can't be used
on a UNC-based path, only on DOS compatible (drive letter
assummed) based-path.
