Yes, I see the same going back to vim74. Interestingly traditional ex-vi
behaves the same, while nvi jumps by each single "a" forward (which is
also confusing: on a line like this:
aaaaaa
and then searching for aa and hitting n
the cursor will move only by a single a forward, while I would expect it
to move by 2 "a")
Ah, I see, thanks for the results on different editors.
Though out of the norm, I like the nvi behavior. Glad to know that vim
also could mimic that.
I checked the POSIX specs, but it doesn't mention anything about it (or
I did not find it).

It's hard to find and hard to understand, but :h cpo-c let's you
configure this.
I had a hunch (or maybe I read sometime ago) that it would be in cpo, but thanks for pointing
out exactly where it is. Though I want that behavior, I will just use that on a need
basis. I am sure it is going to break many plugins if I turn it on unconditionally.
Thanks again Christian!

Heck, Democrats don't question the Republican's right to govern even when
Democrats win elections.
