[Bug 1811240] [NEW] "journalctl -n1000 -r" does not do what you would expect

[Jonathan Kamens]

Public bug reported:

I would expect "journalctl -n1000 -r" to display the most recent 1000
log entries in reverse order.

Instead, what it appears to do is skip over the 1000 most recent log
entries and display the 1001st - 2000th log entries in reverse order.
