thanks, this looks useful.

handling Versions file would be useful.
(and Makefile too, but that's harder)

other things i noticed:

if a commit has multiple authors currently that's only
tracked in the changelog, so there needs to be a way to
somehow specify multiple authors in git commits to
correctly generate the changelog.

if something is changed under an #if conditional, that
condition may be more than 80 chars, but currently the
script prints it on a single line.

if a function is renamed it says it's removed and a new
function is added with the new name.

it cannot tell if a file is rewritten from scratch and
then it may generate a large changelog instead of just
saying "Rewritten".
