I haven't been active on this list. I apologize if reviving a year-
old post violates list etiquette, but it seems like the easiest way to
reference the issue.
I for one am one of those poor misguided souls who quite regularly
abused this accidental side effect. I was rather disturbed by its
disappearance with my recent upgrade from the vim 7.3 shipped with
debian wheezy. I do think this warrants an option, so I've made an
attempt to implement one. This is my first time poking around in
vim's innards. I'd love to get some feedback. Did I do this right?
Would a different name make more sense? Also, is there any chance of
getting this patch accepted? I am reasonably certain that there are
quite a few of those people who prefer the earlier behavior.
Thank you and best regards,
Aryeh Leib Taurog

made for the delete operator with these movement commands: |%|, |(|, |)|, |`|,
|/|, |?|, |n|, |N|, |{| and |}|. Register "1 is always used then (this is Vi
compatible). The "- register is used as well if the delete is within a line.
+If 'regone' is set, both registers "1 and "- will always be used for small
+deletes, regardless of the movement commands used (this option is not Vi

With each successive deletion or change, Vim shifts the previous contents
of register 1 into register 2, 2 into 3, and so forth, losing the previous
contents of register 9.
