(This is a followup because initially I wanted to talk about this in my
other mail, and subject are near.)

Something I wished existed out of the box with rectangular-selection, is
C-e (`move-end-of-line') going not at the end of the current line, but
at “max pos” horizontally, that is, on the current line, n chars away
where n is the number of chars of the longest line in (I guess,
non-rectangular) region.  As C-e is often used, I wished its first call
went at the end-of-line, and only a second times it will go at a such
position.

I had ended up writing something in elisp that takes care of that transparently. Search for ";; Rectangle" in https://github.com/kaushalmodi/.emacs.d/blob/master/setup-files/setup-editing.el.

That code "just works" for few years (I think) now.
