When using -z to compress column width, the loop does not reset the
maximum width for each column, but instead accumulates the maximum width
of all preceeding columns.
For example, the following input
1
a wide column
2
3
4
a
another wide column
b
c
d
passed into rs -ze 0 5 gives
1 a wide column 2 3 4
a another wide column b c d
with the third, fourth, and fifth columns having inherited the maximum
width of the wider second column. I would have expected them to have the
same width as the narrow first column.
With the patch below the output is what I would expect:
1 a wide column 2 3 4
a another wide column b c d
