Extraneous space in code creates "%20" in messagesend result

I'm writing a module which includes the following line:

$ext -> add($context,"sms","",new ext_messagesend("\${ActualTo}","\${MESSAGE(from)}"));

The end result in the dialplan is this:

exten => sms,n,MessageSend(${ActualTo}, ${MESSAGE(from)})

Note the space between the comma and the dollar sign.

When the code is executed, the data received by ${MESSAGE(from)} includes a "%20" at the beginning of it.  When the space is removed, however, the %20 is no longer present.

To fix this, I modified line 508 of /admin/libraries/extensions.class.php, removing the space found in the middle portion of the ternary statement.  You have:

"MessageSend(".$this->to.", ".$this->from.")"

but it needs to be:

"MessageSend(".$this->to.",".$this->from.")"

Thank you!
