[Nano-devel] [PATCH 1/3] display: represent half of a double-width character with "[" and "]"

[Benno Schulenberg]

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 "<", which will be repurposed.)
