Subject: [PATCH] Grid: #### is sized by the width of #, so it fits its cell in
 every font (#2378)

A number too wide for its column is drawn as ####, with as many # as fit. The count used the
width of 0, and in fonts where # is wider than 0 the hashes ran past the cell edge.
accounting_fill::too_wide_fill_number_shows_hashes_not_a_clipped_value caught it on FreeBSD
and on Linux machines without the CI font set.
