Yeah we had discussed using Signed-off-by but I just forgot to implement 
it in this script.  I'll add it.

I haven't put in any smarts to wrap the text because that's just going 
to be painful to implement.  If it's not too bad, I'll take a stab at 
that later.

Yeah that's a known limitation; there's no way for a script to know that 
right now.  Maybe in future one could implement smarts that compare the 
bodies of all added and removed functions and guess that there was a rename.

True, I would consider it an enhancement over the ChangeLog though, if 
knowing exactly what changed is needed.  Maybe if that's considered too 
verbose, I could later look at the possibility of listing differences 
only if the modification percentage is less than a certain threshold. 
Although git doesn't always give that information and we may have to 
compute that first if it's not available.
