      Description

      Moving from velocity engine 1.4 to 1.5, one of my macros is now causing a ParseException:

      #macro( makeLink $filepath )#*

      ##if ($request.serverName.equalsIgnoreCase("www.liveserver.com") || $request.serverName.equalsIgnoreCase("liveserver.com"))#

      ##set($mirrorDomain = "livemirror.com")#

      ##elseif($request.serverName.equalsIgnoreCase("stagingserver.com"))#

      ##set($mirrorDomain = "stagingmirror.com")#

      ##elseif($request.serverName.equalsIgnoreCase("devserver.com") || $request.serverName.equalsIgnoreCase("localhost"))#

      ##set($mirrorDomain = "devmirror.com")#

      ##else#

      ##set($mirrorDomain = "liveserver.com")#

      ##end#

      *#http://$

      {mirrorDomain}

      $

      {filepath}

      #*

      *##end

      This macro uses the mutli-line comment hack to gobble whitespace (so that none appears in the link text, whilst preserving some kind of readability.

      This works fine in 1.4, but throws a ParseException in 1.5 (stacktrace below)
