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
