# when left_border(ht)[i, j] <- value is called,
# first left_border(ht) is called and assigned to (say) lb.
# `[<-`(lb, i, j, value) is then called. The result is (say) lb_new,
# which needs to represent the whole object.
# Finally, `left_border<-`(ht, value = lb_new) is called. The result
# is assigned to ht!
#
# Plan: `left_border` returns a brdr() object.
# `[<-.brder` returns another brdr.
# `left_border<-` copes with both brdr objects, and matrices of
# thickness, since it is also sometimes called directly.
#
# left_border_style(ht)[1, 3]
# calls left_border_style, calls [<- on the result and then
# calls
# left_border_style<-. So we just make sure
# left_border_style<- and left_border_style talk to the appropriate bit of the
# 3 lists.
