[antlr-interest] found more bugs in ANTLRv3.g + howto add separator when parallel iterating 2 lists in stringtemplate

[Jens Boeykens]

Another detail for rule rewrite_tree_atom that I am not sure if it is
correct:

In ANTLRv3.g :               ^(TOKEN_REF ARG_ACTION?)
In ANTLRv3Tree.g:         ^(TOKEN_REF ARG_ACTION)

The question mark dissapeared.  I added  it  in my code, but  not sure if it
is necessary...

Another thing I did not understand very well (probably my own fault ;) ) :
There is a rule called "rewrite_template_block" which is defined, but no
other rule seems to be using it. Does this make the rule obsolete? I noticed
this because I have not yet encountered a testcase where the rule was used,
so I am not sure wether I should write more tests or the rule is indeed
obsolete.

Kind regards
