[BUG] array with single reference

[Christoph Reck]

Mr. Parser is unhappy again if you tell him to look over an
array with a single reference:

#set( $foo = [ $list ] )

and emits:
 Wed Feb 07 16:58:04 CET 2001  [error] Parser Exception: example.vm : 
org.apache.velocity.runtime.parser.ParseException: Encountered "]   )\n" at line 19, 
column 22.
Was expecting one of:
    ".." ...
    "," ...
    "]" <WHITESPACE> "=" ...
        at 
org.apache.velocity.runtime.parser.Parser.generateParseException(Parser.java:3161)
        at org.apache.velocity.runtime.parser.Parser.jj_consume_token(Parser.java:3045)
        at org.apache.velocity.runtime.parser.Parser.IntegerRange(Parser.java:813)


Ugly workaround:
#set( $foo = [ "", $list ] )
#call( $foo.remove(0) )
