Feature request---Lines.

[Mark Summerfield]

Lout has @FullWidthRule (and @LocalWidthRule). 

But I can't see a straightforward way to do lines with dots, dashes,
etc. (I can think of ways of doing it, but none that are nice and
easy.) Both these symbols has a linewidth option; would it be possible
to have a character option that defaulted to '-' (which signified a pure
line), but that offered '=' (a double line), or a character or symbol of
the user's choice in which case that symbol would be used?
