From 4e7c882c3cb709d8d7a52d10c6d4f31f698b0e05 Mon Sep 17 00:00:00 2001 From: Zane Bitter Date: Sat, 5 Jun 2021 21:30:05 -0400 Subject: Automatically page interactive root help output The previous commit already ensures that the interactive help for individual commands is sent to a pager. This does the same for the 'help' command with no arguments.
