This would seem to indicate a requirement for two different bind options,
the existing one that assumes the sub-process does not interact with the
terminal (or expects the terminal to be in raw mode), and a new one that
provides a shortcut for "replace the current input buffer and submit it as
if the user had pressed enter".

Then again, one could simply define the function key as ^E^Ufg^J

Perhaps what's really needed is to make sure that "ordinary" commands bound
using bash -x are completely broken (so people won't try to use them),
rather than almost working.
