[antlr-interest] ISSUE: Global comments lost with grammar inheritance

[micheal_jor <open.zone at virgin.net>]

DESCRIPTION:

When using the grammar inheritance feature of ANTLR, "global" 
comments (i.e. comment blocks that immediately preceed the grammar 
class definition) do not appear in the generated file.
These comments would normally appear in the generated file just 
before the class definition.

TO REPRODUCE THIS ISSUE:

Given the grammar files at the end of this message, when the ANTLR 
tool is invoked on both file (using the -glib option as appropriate):

1. the generated BaseLexer.cs files has the C# XML comment included 
in it's source grammar file base.g. Cool.

2. the C# XML comment is missing from the generated DerivedLexer.cs 
file (and also from the generated temp-ish file 
expandedDerivedLexer.g). Uncool.


ATTACHED FILES:

------ BEGIN base.g ----
options
{
  language = "CSharp";
}

///<summary>
/// Base Lexer summary description.
///</summary>

class BaseLexer extends Lexer;

BASERULE
: "base"
;

------ END   base.g ----

------ BEGIN derived.g ----
options
{
  language = "CSharp";
}

///<summary>
/// Derived Lexer summary description.
///</summary>

class DerivedLexer extends BaseLexer;

NEWRULE
: "derived"
;

------ END   derived.g ----

OK, we *need* a bug/feature/issue/reqmt tracking app.
