DIRECTOR: Support "me(blah 1, 2)" syntax, e.g. no comma after the method name

This is used in totaldistortion-win

   --start-movie="ATD\HD\bdDREAML.DXR"

When the bulb explodes, the Lingo tries to execute a constructed
   do("me(bubdie2 5, 75)")

which then leads to syntax error.

The original allowed this broken Lingo syntax
