Older versions of cygstart did not replace the file names with absolute 
windows paths. This was better since the ShellExecute function will 
search the path for a command. And, if it doesn't find it in the path, 
it will look in the registry. So you can 'cygstart calc', 'cygstart 
winword', 'cygstart services.msc', etc.

This can be accomplished by changing
  CCP_POSIX_TO_WIN_W
to
  CCP_POSIX_TO_WIN_W|CCP_RELATIVE
the two places it appears.

Interestingly, ShellExecute also accepts certain non-filename strings 
for "shell namespace objects".

For example:

Drives (My computer)
::{20D04FE0-3AEA-1069-A2D8-08002B30309D}

Control Panel
::{20D04FE0-3AEA-1069-A2D8-08002B30309D}\::{21EC2020-3AEA-1069-A2DD-08002B30309D}

You can try these out with the Run command on the Windows start menu or 
the CMD.EXE  START command.

This last one doesn't work in cygstart even after the CCP_RELATIVE 
change is made. This is not because of any bug in cygstart, though, so 
I'll save it for another email.
