[CodeQuality] Split else under throw

[TomasVotruba]

Suggested by PHPStorm:

if( ! preg_match( $this->regDQuote, $this->src, $r ) ){
    throw new Exception( "Unterminated string constant on line $this->line" );
-} else {
+}
-    $s = $r[0];
+$s = $r[0];
-    $t = Tokens::J_STRING_LITERAL;
+$t = Tokens::J_STRING_LITERAL;
-}

Also, you can check for return, continue statements before the else branch.

for .......
  if(...){
    continue; 
  }else{ // << -- you can remove else. 
  }
