We already rely on this symbol in these scripts, so might use it to
display the mathematically correct ratio for new entries.
This has the added benefit of ordering new entries vs extremely big
changes correctly:
$ ./scripts/code.py -u test.after.csv -d test.before.csv
function (1 added, 0 removed) osize nsize dsize
test_a - 49 +49 (+∞%)
test_b 19 719 +700 (+3684.2%)
test_c 91 191 +100 (+109.9%)
TOTAL 110 959 +849 (+771.8%)
