Given the single way that print_line_middle()
is called in the source code, it's implicit that
this is about --only-matching and --color, and
we know what it is these options do.  A patch to
this function can only be about that.  Already,
mentioning print_line_middle() covers this and
the ChangeLog entry is not there to redundantly
document the existing source code.  Taking this
into account before reading any further beyond
the first ":", the existing comment is IMO
sufficient.

They were not displayed or colorized before,
so there is no change in behavior there.
This unchanged behavior may differ from expected
behavior, but that's an eye-of-the-beholder
issue and what's unchanged doesn't belong in a
_change_ log.

The ChangeLog entry does mention that these GNU
extensions were otherwise unspecified and that
was the real problem.  Who's to say what's a
bug or a feature before they are, then?
