You're going to have to redirect the process's output to read the
shell's output and then use it to fill the user's current input.

The better way (IMNSHO) is to catch the process output so it doesn't get
inserted in the buffer, build a completion table from it, and then
call the normal in-buffer completion code with it so it gets displayed
in *Completions*.

I don't know if someone ever tried to use a term rather than a comint
inferior process, but I'd be interested to hear your experience with it.
I suspect it's going to be harder to interface it with compile.el.
