Good. I'll concentrate on option 4 in the next few days. This part is
needed for option 3 as well.

OK. I think Eli's immediate needs will be fulfilled by option 4
(system-quote.h), but if you want to implement option 3 (popenv, systemv)
on top of that, feel free to.
For applications that want the optimized code - no use of /bin/sh and
use of vfork() if possible - we currently have the 'execute' and 'spawn-pipe'
modules; so the current situation is not that bad. (It would be even better
if we had a posix_spawn that works also on mingw. Has been on my TODO list
for ages...)
