Ugh. That was horribly broken, and sadly I didn't notice until several
pulls later (I tend to try to compile-test much more often, but do
boot-tests only a couple of times a day).

You clearly hadn't tested that patch at all, the resulting signature
was broken in two independent and totally different ways.

Tssk. I fixed it up, and now it works-for-me(tm), but some perl person
probably really should try to make that sign-file and x509keyid merge.
My fix made the thing even slower, doing two extra "wc -c" invocations
since it can't do "${#..}" expansion due to the locale problem.
