Hi,

I Have a block like below. It will produce the following output when 
included with the 'collapse' filter.:

"- name1 , name2 , and name 3 en".

I need to get rid of the space in front of comas, but cannot figure out 
a way to do it. I tried all possible combinations of TRIM and CHOMP 
options., Both globally and on tag levels to no avail.
Any help would be appreciated.


     -   [% FOREACH author IN COLUMN.list_authors %]

      [% IF loop.last %]

        [% IF COLUMN.number_of_authors  == 2 %] and [% END %]
        [% IF COLUMN.number_of_authors > 2 %], and [% END %]

        [% author.get_name(LANGUAGE) %]
      [% ELSIF loop.first %]

      [% author.get_name(LANGUAGE) %]

      [% ELSE %]
      , [% author.get_name(LANGUAGE) %]
      [% END %]

      [% END # of authors loop%]
