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.
