Lynx+vi 

Being a long-time WP editor, I recently started using Lynx and VIM for editing and discovered a few caveats after some real-life usage, which are now noted in Wikipedia:Text editor support#Lynx (the most recent being line breakage). The reason I am making note of this, is that I might have accidentally saved a few sections with unintentional carriage return breaks. I was not aware of such program behaviour beforehand. -
