From 814ca9ffea229f55f1f69b34d9a7f84054115669 Mon Sep 17 00:00:00 2001 From: zeripath Date: Sun, 24 May 2020 09:14:26 +0100 Subject: [PATCH] Allow different HardBreaks settings for documents and comments (#11515) GH has different HardBreaks behaviour for markdown comments and documents. Comments have hard breaks and documents have soft breaks - therefore Gitea's rendering will always be different from GH's if we only provide one setting. Here we split the setting in to two - one for documents and one for comments and other things.
