That looks funny. But I dont like it.
It appears to be fixed in 11-STABLE (r321419).

I don't think so. At least there is nothing in the commitlog. r318449 is the
last commit in 11-STABLE for the respective file; and thats before the
11.1-RELEASE branch.
See r321419.
Yes, thats the issue with the empty line when ZFS is *not* in use, which
I mentioned below (bug #220996). For that a fix is committed.
The error is in the screen-formatting in "top", and that error was already
present back in 1997 (and probably earlier), and it is also present in HEAD.
What "top" does is basically this:
char *string = some_buffer_to_print;
printf("%.5s", &string[-4]);
A negative index on a string usually yields a nullified area. (Except if
otherwise *eg*) Thats why we usually don't see the matter - nullbytes are
invisible on screen.
Fix is very simple:

Then, concerning the complaint about the empty line (bug #220996), I
couldn't really reproduce this. But it seems that specifically this issue
was already fixed in HEAD by this one here:
https://reviews.freebsd.org/D11693

Now, can anybody make the above snippets appear in HEAD and 11-STABLE?
I've CC'd allanjude, who has touched some of these in the past.
Thanks a lot!
