Substantial patch

This patch is larger then it looks due to my editor judiciously removing
trailing space in write.c.  The patch passes regression testing.  I modified
the way we handle disabling delimiters for writing the namelist narrative.  I
also made use of the DELIM_UNSPECIFIED to indicate defaulting to "quote".

I will post to list for approval on my next opportunity.
