Since I'm already dealing with the fish shell.
All of our supported shells seem to handle cursor position
in Unicode (wide character) codepoints.
It was easiest and most straight-forward to pass the data
through yet-unused program arguments.
The cursor position is marked by a Unicode glyph equivalent
to ACS_DIAMOND, although ncurses doesn't get a chance
to make any ACS translation.
