Yes. Did you read my whole mail?

See, that’s sort of the problem. When you could use something simple like
% repeat 10000000; do echo "this is a fucking long line?"; done > test
you’re already thinking of a C program, 13 lines long.

”Logical”? Am I getting my terminology mixed up or isn’t a logical
line what you get when you enable word wrapping?
By the way, Emacs has the exact same issue with this sort of file.

I don’t follow this line of reasoning.

This is a desirable goal, yes. Having an editor support transactions
is a good goal and would allow background processing.

Now you’re losing me again. What does this matter? Copy-on-write?
It seems that you’ve just read a book on operating-system design or
something and want to, ahem, rewrite Emacs.

Ah, there it is.

May I then beg you to create a separate mailing list where discussion
revolving around this operating-system Vim can be had instead?

Hasn’t this also been done?.

Memory manager for what memory use?

Huh? What’s wrong with Vim’s undo?

This I can live with.
By the way, I still haven’t written the article I was going to write
on this, but Vim’s current :syntax command is powerful enough to parse
LALR(1) grammars, and perhaps others as well, in a recursive descent
fashion.

You’re tone suggests that this is easy. Invent a language? And how
does that solve all the “problems” listed above?
