Re: wrapping in extended mode doesn't work well with default pager

I'm trying to review all the combinations of the options exhaustively
but in the process I noticed a few pre-existing psql oddities. Both of
these are present in 9.3:

Can anyone explain this? It's linestyle=old-style, border=1,
expanded=off, format=aligned. It looks like it's using new-style ascii
indicators in the header but old-style in the data cells:
         a           |         a
+                     |+        b
+         b           |+
----------------------+--------------------xx                   | yyyyyyyyyyyyyyyyyyxxxx                 |
yyyyyyyyyyyyyyyyxxxxxx              : yyyyyyyyyyyyyyxxxxxxxx             : yyyyyyyyyyyyxxxxxxxxxx           :
yyyyyyyyyyxxxxxxxxxxxx        : yyyyyyyyxxxxxxxxxxxxxx       : yyyyyyxxxxxxxxxxxxxxxx     : yyyyxxxxxxxxxxxxxxxxxx   :
yyxxxxxxxxxxxxxxxxxxxx:

Also the line-ending white-space is very odd here. It's
linestyle=old-ascii, border=0, expanded=off, format=aligned. There's
an extra space on the header and the first line of the data, but not
on the subsequent lines of the data:
        a                   a                   +        b        b          +
