I just did a test where I created a file, xit, with the here document in 
it and ran it with ./xit

This way, the tabs remained.  So the 'problem' is when I am pasting the 
same lines (with tabs) into the terminal window.  There bash is 
interpreting the tabs and not feeding them into the here doc processing.
