My preliminary reading (I sadly lack the time to pull your branch and play
with it) suggests that this works, although I have to admit that X/Y/Z
would confuse me in 6 months from now, as they do not really read like
diff markers but like plain text. I could imagine that '>', '<' and '#'
would not impart that confusion on me.
Ciao,
