Are you sure?

Why do we still need this line?

Why this unrelated change? is something wrong with the original code?

I've read this part of the comment many times, and I still don't
understand what you are trying to convey there, and thus don't
understand the new 'if' clause you added. In particular, how come
this was never something brought to our attention? the comment seems
to imply that replace-match was somehow badly broken since forever.
And please don't use Markdown's markup in our code.
Still confused...
