Indeed, as I thought about it more, using a "no-op" todo editor seemed 
like a good approach.  Thanks for giving me a head start - I'll play 
with that and try to get a new patch with an improved test posted in the 
next couple of days.

One question about my original patch - there I had replaced a "grep -v" 
call with a "git stripspace" call in the 'generate correct todo list' 
test.  Is relying on "git stripspace" in a test acceptable, or should 
external text manipulation tools like grep, sed etc. be preferred?

Thanks,

Daniel Harding
