Well, my guess is that blank lines are a leftover from processing of
Interchange tags which return no value. And that whitespace isn't 
all newlines, there are some spaces on those lines.

So try something like =~ s/\s*\n+\s*/\n/g;

No, I mean htmltidy or indent.. external programs used for formatting
input, and not related to apache in any way.

They are probably slow to run and all, so you won't want them on a
busy site.
