My apologies, I was just so excited that I'd finally finished it!
Apparently I missed a few things, thanks very much for catching
it.

This is cleaner, thanks. In fact, I don't even really need the
shift at all.

Sure, may as well, save a subshell.

In general I've used them everywhere... except there :) Fixed.

It hasn't been so far - The convention in all known cases is
either it's all on one line, or a multi-line as is caught by the
second sed expression. This is just a stopgap measure until I
rework 0distutils to do this optional stripping on its own.

Not if I want to potentially die on the assignment. As I found
out in #gentoo-dev-help today, try this:
$ t() { local a=$(false) || echo "Die"; }; t
Versus this:
$ t() { local a; a=$(false) || echo "Die"; }; t
Die

Verily - nice catch!

Sure, that looks nicer.
I'll be committing these changes right away, since the "die" ones
at least are very important. But I'll be submitting further
changes to the list first. Sorry about that :)
Luckily only 1 ebuild so far which uses this eclass has actually
hit the tree!
