Well, I'm a bit confused.  The above doesn't look like a template file, so I'm
not sure I'm actually answering your question, but I tried a couple of things.

1.  I put the above <template></template> lines in a file named qt.tmpl,
and ran the following code:

     1  #!/usr/local/bin/perl
     2
     3  use strict;
     4  use warnings;
     5  use HTML::Template;
     6
     7  my $template = HTML::Template->new( filename => "qt.tmpl" );
     8  my $stuff = $template->output;
     9  print $stuff;

I got the following output:

##########################################
=> this represents line 1
=> this represents line 2
=> this represents line 3
=> this represents line 4
=> this represents line 5
##########################################

(Question: is that *really* your template file contents?)


2. The problem you describe reminds me of the classic beef about
extra line breaks when a template is filled in.  Of course, these
aren't really *extra*, because the template file contains them.  For
example, when I run the following code:

     1  #!/usr/local/bin/perl
     2
     3  use strict;
     4  use warnings;
     5  use HTML::Template;
     6
     7  my @array = <DATA>;
     8  my $template = HTML::Template->new( arrayref => \@array );
     9  $template->param( loop => [
    10      {line => "line1"},
    11      {line => "line2"},
    12      {line => "line3"},
    13      ] );
    14  my $stuff = $template->output;
    15  print $stuff;
    16
    17  __DATA__
    18  ##########################################
    19  <TMPL_LOOP name="loop">
    20  <TMPL_VAR name="line">
    21  </TMPL_LOOP>
    22  ##########################################

I get the following output:

##########################################

line1

line2

line3

##########################################

A template novice might complain that HTML::Template is adding extra
line breaks, but of course, they are right there in the template.  I don't
think that you're a template novice, so again I'm not sure this is answering
your question.

You say that nothing in your templates has changed.  However,
I don't think you have given a real example of one of these templates,
so beyond my guesses above, it's hard for me to know what will help.
