Incorrect reporting of some errors

[joetesta]

For each of the following two cases, an error is incorrectly reported as

Parsing error: mismatched input 'sub' expecting <EOF>

1. sub with non-void return

sub dostuff() as Object
end sub

2. print followed with elements separated by comma

sub dostuff()
  print "Restarting app", appStoreID
end sub

Looks like these can only be reproduced when they preceded by a valid sub declaration.

sub dummy()
end sub

sub dostuff() as Object
end sub

#107 should be addressing this issue. It looks like the problem was the parser bailed out early whenever it tried to complete parsing the following sub block.
