I often work with diffs in Emacs. I usually do that within Magit, which highlights diffs in the usual way (highlighting deleted lines with reddish background, inserted lines with greenish background, and the deleted/inserted characters within these lines with slightly more prominent versions of the same colors). However, I sometimes use plain Emacs diff (e.g. to compare two fles not kept in Git), and I noticed an annoying thing: diff’s font-lock is applied on top of the usual font-lock, depending on the files’ syntax. While in general this seems resonable, in the case of LaTeX files in AUCTeX (where the font lock colors are especially diverse) this makes the diff completely unreadable. I was pretty sure that disabling the syntax font-lock would reduce the visual noise of the diffs.
