This version fixes some bugs I had noticed in expanded mode too. For instance,
the original looked like this (five lines plus header):

-[ RECORD 49 ]-----+-------------------------------------------------------------------------
pg_identify_object | (rule,,,"""_RETURN"" on pg_catalog.pg_available_extension_versions")

pg_identify_object | (view,pg_catalog,pg_available_extension_versions,pg_catalog.pg_availabl
e.
|._extension_versions)

whereas it's correctly only three lines plus header with this patch
applied. I can't tell whether this patch is minimal enough.

Having a more comprehensive test case is good, of course, though I
didn't check the expected file. Note that some things cannot be tested
correctly in this way, namely column count that actually match the
terminal -- to wit: I had to add line breaks manually to the above paste
so that it would look like what it does in my terminal. If I just paste
it, it looks correct, but then my email terminal is wider than the one I
ran psql in. I would presume that failure to account for this is what
caused (some of?) the bugs being fixed now ...
