Honestly, I don't really understand the code that emerge uses to restart
itself. Basically, the current behavior is to restart itself with a filtered
version of it's original arguments. It seems to be error prone and I don't see
how it can handle all of the necessary cases.
The attached patch uses the existing "--resume" functionality to solve the
problem. The new argument list is generated from "myopts" and selected
"badlongopts" are
filtered out. I've been using this patch locally with no issues. Feedback
would be appreciated.
