Some modes (at least python.el) do their own input coloring according to
the major mode font locking rules. It's unfortunate that comint then
overwrites this coloring with comint-highlight-input face. Now, avoding
this is as simple as removing

    (add-text-properties beg end
                         '(front-sticky t
                           font-lock-face comint-highlight-input))

from comint-send-input. The problem is that these 3 lines are buried
down into a long function and it's not possible to cleanly disable them,
except maybe by an around advice that redefines add-text-properties.

There is an even more unfortunate consequence of this: for multiline
inputs all but the last line will be fontified by
comint-highlight-input. I had reported that in which now I'm going
to close since it's obviously a particular manifestation of comint
forcing the recoloring of previous inputs.

Please add a customization variable to make this behavior optional so
that modes that colorize input can keep their colors in previous inputs
and in previous lines of the current input.
