I wonder, seriously, how many (if any) users of H and L had previously
run into this problem to be aware of what you consider "inconsistency".

Because as I noted yesterday, H and L are, I think, the ONLY vi
movements that are about what-is-currently-displayed. Everything else
is about searches, straight out character or line counts, marked
positions, and explicit positions.

I include find-match "%", end-of-paragraph "}", find-character "f"/"t",
etc, in "searches"; start-of-line-test "^" possibly that or else
"explicit positions" like character "|", end-of-line "$", start-of-line
"0", and end-of-file "G". And marked positions either named (eg "`a") or
implicit (eg "''") don't change depending on view or cursor position.

And I don't include any movements that are in vim, but not vi. (Not that
I can think of any relevant for this point, but I know there's a lot in
vim I don't use.)

H and L are always the top of the view and the bottom of the view. And
they change when the *window changes size*. They are nothing like the
other vi (real vi) movements. (M, too, changes with window size, but M is
not really affected by scrolloff.)

I've been using vim since just about forever, I know have vim 2.x around
in my archives, and still sometimes think about changes like "Q" becoming
"gq". But I use vim in a very vi-like way, not in a very vim-ish way. So
how vim features interact with vi features might be more concerning to me.
