On my Ubuntu system:

mawk 1.3.3 Nov 1996, Copyright (C) Michael D. Brennan

this line:

    nlines == 0 && !/[^[:space:]]/ { next }

skips all lines, so I end up with "Empty change log entry" and an abort.
For now I've removed it because I don't know awk well, so I can't fix it
properly myself.

I can rewrite that script in Perl if it's better.  Whatever works.
