I was trying to avoid this in favour of psvar, but I think it might be
the best way to do this.

I have just a couple more problems. Firstly I can't find a way to have
ANSI escape sequences actually executed when they are passed through
psvar - is this possible?

And secondly with
    "%\$((\$COLUMNS-2))>%{%}k>"
the %{%} appear in the prompt and both
    "%\$((\$COLUMNS-2))>${(%%):-%{$fg_bold[cyan]%\}}k>"
and "%\$((\$COLUMNS-2))>\${(%%):-%{$fg_bold[cyan]%\}}k>"
seem to be counting the length of the ANSI escape sequence in the length
calculation - am I missing something?


Thanks
Ian, who's slowly getting there  :-)
