[stringtemplate-interest] "\n" goes away

[Terence Parr]

Hi, i allowed

<expr; separator="\n">

previously to mean newline separator, but that makes no sense.  "\n"  
is a 2 char sequence just like it is in between template expressions.   
But making you do

<expr; separator={<\n>}>

is a bit long.  It's *always* comma or newline. seems we should make  
it easier to say.  we use it constantly.

As far as i can tell, we have these options: wrap, anchor, null,  
separator, format.  Is there a better way to do those too?  How would  
we do this differently?

<values; anchor, wrap="\n", separator=",">

Ideas?  I've wrestled with this for years and can't come up with  
better syntax.
