[PATCH] eww-open-in-new-buffer

From: Mark Oteiza
Subject: [PATCH] eww-open-in-new-buffer
Date: Tue, 01 Nov 2016 22:03:18 -0400


I wanted something akin to "open in new tab" for eww, so I wrote the

M-RET seemed a good binding.  One thing that bugs me about this is that
eww-current-url in eww-suggest-uris didn't quite fit: as the new
function is, it doesn't make sense if url is (eww-current-url).

So, I made changes to eww-suggest-uris.  Alternatively,
eww-open-in-new-buffer could check if url is equal to eww-current-url
and just clone instead of invoking eww.  That might be better.
