In case you wonder which patch i'm talking about, here it is.
Note this is not against -current, but against the backed-out
version for brevity.
Not fishing for OKs at this time, just FYI.

Log message:
Backout previous, naddy@ found the following regression:
When the input does not end in a trailing newline character
and there is an empty match at the end, the new code adds
a spurious '\0' character.
I have a fix, but otto@ prefers backout and full re-evaluation
after release.
