The length of those fields does not depend on the number of packages we
have. We can have just a few, and be close to the maximum expected width.
And unfiltered find is likely to get very busy indeed, because you'll
always be hitting the worst possible width available for all fields.
Eventually we should likely prevent that command from running altogether.

Looking at my 16.04 installation for more relevant data, the max length for
versions is 52, but the average is 12 and the median is 7. The output of
unfiltered dpkg -l starts the summary at column 129, despite displaying
only the name, version, arch, and summary.

I don't think we can win if the goal is having meaningful output for
everything under 80 columns.
