True.  Welcome to Win32!

rm is part of the fileutils package.  You can download the source there if
you'd like to look at them.  Coding standards are GNU.  Sorry, I don't
have a pointer for those.  You can look at 
http://www.cygwin.com/contrib.html for pointers on Cygwin contributions 
however.  I suspect you're going to find that you'll need to look at the 
Cygwin DLL source to make a change along the lines of what you suggest
though.  Its the Cygwin DLL that handles figuring out how emulate the 
desired behavior.  The Contributing page will tell you what you need to 
get started building the Cygwin DLL too.

Have fun! :-)
