I implemented a similar way. The above hadn't recognised things like
pasting in the contents of the clipboard. It could have been captured
with the paste-clipboard signal but only when using the popup menu,
when using Shift-Insert for pasting, the VTE didn't know this.
So, I used the VTE commit signal which sets the VTE as not clean, only
pressing Enter/Return and the restart of the VTE mark it as clean
again. An error message is printed when vte_send_cmd() is called on a
non-clean VTE(maybe the message could be improved?).

I hope this will work in all cases, at least it is independent from the
shell which is running in the VTE.

Yes, but I don't know how to catch such cases and the user should also
take a little care of what he is doing.

Hehe, or a bored user define
alias cd="rm -rf"
I guess somewhere are limits of what we can do to work around user's
negligence.
