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.

Found this while testing the C++ conversion for vec.[ch] on the
cxx-conversion branch. We do not build the build/*.o files with g++,
so I was getting lots of syntax errors while compiling build/vec.o.
