One thing that bash does is *deliberately* compute the line break one
character *before* the edge of the screen.  You can see what happens when
it is fooled into thinking the prompt is 1 character shorter than it
actually is (e.g., "export PS1='$\[ \]'" and type a long command).

Most shells understand "`""`" (particularly, all official shells on
Cygwin, which is what's important).  In fact, in this particular case,
it's probably better to use "``" instead of `""`, IMO.

Good point.
