Yes, but last time I tried to grok tramp's internals, it took me a long
time.  Can you give me a function stub, which I will fill in, to do
generic filtering of process data before Tramp's handlers see it?  If
it's a simple pipe function, I can write the code to filter ANSI
sequences out.  I think it should simply be

(defun tramp-io-filter data &optional term &rest options)

Where DATA is the string, and TERM defaults to something minimal like
vt100.

I'd rather not rely on external code for this because we need to be very
flexible, handling unexpected sequences and terminal bugs in the
future.  I hope you agree.
