This script analyzes a .diff file and generates a skeleton ChangeLog
entry for it.  It tries fairly hard to find function names, so it's
important to use the -p switch with diff.

I wrote the initial code a while ago.  Cary added a bunch of smarts to
make it understand C++ and guess the function names better than the
original version.
