Actually, I just tried this with both log_input and log_output options enabled.
It seems that it *can* see into the promoted shell with a few caveats:
- Command output is logged immediately, but command inputs appear to only
be written to the log when you exit the promoted shell. This may be
not quite right - there may have not been enough input to cause a
write flush to the log.
- The logging seems to be able to see into a spawned subshell, but
I don't think it can see input/output if you, say, kick off an xterm.
