Author: 0mp (ports committer) Date: Sat Sep 21 15:01:11 2019 New Revision: 352578 URL: https://svnweb.freebsd.org/changeset/base/352578 Log: jot.1: Explain default argument values more precisely The way jot(1) defaults missing arguments doesn't match the behaviour described in the manpage, which states that with fewer than 3 arguments missing values are supplied from left to right. In fact, with one or two arguments, the last (s which is step size or seed) defaults to 1 (or -1 if begin and end specify a descending range), and then omitted arguments are set to default starting with the leftmost until three arguments are available. This is why `jot 2 1000` prints 1000 and 1001 instead of 1000 and 100.
