Re: Need testers for mg dired diff

[Loganaden Velvindron]

This is what you're talking about. C-n & C-p
warp the dot on the filename. I've overwritten
the default forwline() and backline() functions.

I like this.

If others don't find it annoying, we can go forward.

I'll look at another issue that Mark brought up
when I'll be done with work.
