True, if you are editing it's a different thing from browsing.
My program split the GEDCOM into level zero records, and put
them into a BerkeleyDB with the @xref@ as the key (HEAD and TRLR
used their tags as the key).

So although the stoage medium was not a single GEDCOM file, the
records remained in GEDCOM. And output was merely pulling the
desired records and concatenating them.

Doesn't need it. That's the job of the lower level routines.

I don't worry myself in vi about what happens under the hood
when I add characters to a line.

The genealogy application should deal with the data (whether GEDCOM
or other format) and let the XML API or text file API or SQL DB
or whatever maintain the storage format for that data.
