display: represent half of a double-width character with "[" and "]"

When the screen's edge leaves just one column for a two-column
character, then show its left half as "[" and its right half as "]".

(They used to be shown as ">" and "<", but these characters will be
repurposed in the next commit.)

This addresses https://savannah.gnu.org/bugs/?55657.
