I don't see any harm in adding that, seems like a good thing to support IMO
I always thought mobile links will normally redirected to normal links if we are using browsers in desktop but will not be vice versa / the other wway around. So, I think it should be good to add that.
Alright, PR sent: https://github.com/elkarte/Elkarte/pull/2980
PS When I said "someone might post" of course I meant "someone posted this a few hours ago". :P
Merged, I'll grab it for RC2 that I hope to pack today.
