[horde] devtools/horde-js-compress.php generated files missing final semicolon?

[Liam Hoekenga]

I'm trying to rebuild various "js" files from their "js/src"  
originals, and I've noticed something weird.  I don't know if it  
matters, but the files that Horde ships all have a semicolon as the  
final character before the EOL.  When I regenerate the files using  
devtools/horde-js-compress.php, my files are identical save that last  
semicolon.

I'm using

  * $Horde: framework/devtools/horde-js-compress.php,v 1.15 2008/05/14

with a yuicompressor.jar from the end of January.

Is there a command I need to pass to get that trailing semicolon?   
Does it matter if it's not there?
