Further tweaking of print_aligned_vertical().
Don't force the data width to extend all the way to the right margin if itdoesn't need to. This reverts the behavior in non-wrapping cases to bewhat it was in 9.4. Also, make the logic that ensures the data line widthis at least equal to the record-header line width a little less obscure.In passing, avoid possible calculation of log10(0). Probably that'sharmless, given the lack of field complaints, but it seems risky:conversion of NaN to an integer isn't well defined.
