Yes, there is interest, but it should be done correctly. Currently this
is difficult because the marker hack to indicate the beginning and the
end of an escape sequence so that it is not counted as a cursor position
does not work properly. Instead it should be replaced with something that
works (perhaps an adjacent data structure that holds pointers to ANSI
escape sequences or NULL for each character position in the line. That is
memory expensive, but easy to implement.
