There's a slight issue with the inverted cell representing
the cursor standing out a bit too much amongst the rest of
the characters.
The resulting experience is a lot more consistent, though.
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.
I've come to the conclusion that copyright mostly just stands in the way
of software development. In my jurisdiction I cannot give up my own
copyright and 0BSD seems to be the closest thing to public domain.
The updated mail address, also used in my author/committer lines,
is shorter and looks nicer. People rarely interact anyway.
