It's not needed to invoke bash with the -e option.

This patch is super simple :) Basically, the first command of the install-reddit.sh file is "set -e". Therefore, we don't have to invoke bash with "#!/bin/bash -e". We can either remove the -e from the "#!/bin/bash -e" or we can remove "set -e". I prefer removing "set -e" because it's more explicit.
