bug#47489: 28.0.50; [Elpa] Two issues in ztree-diff.el

[Michael Heerdegen]

Hello,

I have two small issues with ztree-diff:

(1) [Bug] The difference buffer view of `ztree-diff' has a problem: the
roots of the two directory trees both show the name of the "Right"
directory, although the diff itself looks correctly.

(2) [Wishlist] Can we please make the relevant keys more visible (like
C, h, H, D, v, d, r, R)?  They don't appear in C-h m, and there is not a
menu, so one has to consult some non-interactive source to look them
up.  I suggest to list them in the header, right along the "Legend".

With those two things fixed `ztree-diff' would be a directory comparison
tool of choice for me.

Regards, and TIA,

Michael.
