Of course it doesn't know how "non-printing" (or text that doesn't
generate a physical position as in the set-icon+title function). So I
thought that it should be able to understand that a "CR" would
return/reset the column to zero. That way it could correctly compute
what column it was in.
Bash can know about non-printing characters. Check the "PROMPTING"
section in "man bash"-
\[ begin a sequence of non-printing characters,
which could be used to embed a terminal control sequence into the
prompt
\] end a sequence of non-printing characters
