I pushed the first patch with some revisions.  You had the TokenizedLine
struct containing something that was still a three-level-nesting list,
whereas it only needs to be two levels, and you hadn't updated any of
the comments that the patch falsified.  Also, I figured we might as well
pass the TokenizedLine struct as-is to parse_hba_line and
parse_ident_line, because that was going to be the next step anyway
so they could pass back error messages.

Off to look at the second patch ...
