This prompt hijacks psvar[7] through [9] to avoid having to reset

When setopt nopromptcr is in effect, an ANSI terminal protocol
|

exchange is attempted in order to determine the current cursor

column, and the width of the upper prompt is adjusted accordingly.
|

If your terminal is not ANSI compliant, this may cause unexpected

behavior, and in any case it may consume typeahead. (Recommended

workaround is to setopt promptcr.)
