[stringtemplate-interest] suppressing newlines and empty strings

[David Ray]

Luis,

Thanks for your feedback.  I'm using the Java version (2.2). Here's an 
example:

foo(bar) ::=
<<
hello $bar$
 >>

yum() ::=
<<
$foo(bar="")$
 >>

With this, I get the following error:

    problem parsing template 'yum', line 1:11: unexpected char: '"'

If I replace bar="" with bar="x" or any other non-empty string, 
everything works.  This isn't a show-stopper bug, just kind of annoying :)
