Ah, the problem is that Windows uses "\r\n" as a line separator,
instead of "\n".
The second problem is that TT doesn't recognise and expand "\r" as
a character sequence. This is a bug which you can fix by changing
line ~501 in Template/Parser.pm from
$token =~ s/\\([^\$n])/$1/g;
to
$token =~ s/\\([^\$nr])/$1/g;
Then you can write
[% FILTER replace("(\r\n){2,}", '</p><p>') %]
or without having to patch anything, you can do something like:
[% FILTER replace("(.\n){2,}", '</p><p>') %]
but that is likely to break things if your input text is Unix-like
(i.e. matching the last valid character on a line).
I've patched the distribution source and I'll put a snapshot up on the
web site RSN.
