We've on a number of occasions seen large through to extreemly large
merges (HP comes to mind) and on each occason the contributor,
unprompted, ensure that a correct ChangeLog was included.

We're talking an hour or perhaphs two, and something we're _all_
expected to do willingly.
The way to do this is to ignore the history and just look at the final
diff. A bit of sed'n'sort will in a matter of minutes give the
functions added/deleted bit, leaving just terse verbage of the other
functions changed. Can we do that?

Diego did a very very large (read 4 years of work x many people) merge
of GCC's mainline. When committed it included a very large (but terse)
ChangeLog entry.
