I think we might be also able to remove --unblock-signal,
and just have --default-signal.

I.E. I don't think one would want to set default signal handling,
but leave a signal blocked?  Also I don't think one would
want to unblock a signal, but leave it ignored?
At least not and the level of env just exec()ing a program.
Anyway if those weird cases are needed, they can be achieved
by combining the options.

The attached does that, leaving us with:

--block-signal[=SIG]    block delivery of SIG signal(s) to COMMAND
--default-signal[=SIG]  reset handling of SIG signal(s) to the default
--ignore-signal[=SIG]   set handling of SIG signals(s) to do nothing
--list-signal-handling  list non default signal handling to stderr

cheers,
