ST_Summary starts and ends with a newline

[mwtoews]

Pick your favourite geometry, pass it to ST_Summary and it will both begin and end with \n newline characters.

select st_summary(geometry), regexp_replace(st_summary(geometry), E'\\n', E'\\\\n', 'g')
from (
  select 'SRID=4326;POINT EMPTY'::geometry
  union all select 'MULTIPOLYGON(((0 0 0, 0 1 1, 1 0 2, 0 0 0)), ((10 10 2, 12 10 4, 12 12 3, 10 10 2)))'::geometry
  union all select 'SRID=4326;LINESTRING(0 0 0 0, 1 1 1 1)'::geometry) as foo;

If you use pgAdminIII, you incorrectly see blank lines from ST_Summary, unless you expand the row heights from the default to revel the multitiline output where text begins on the second line.

The output from multiline PostgreSQL functions (e.g., select table_to_xml('geometry_columns', true, true, 'foo');) does not have this behaviour. Newlines should only appear within the text body, and not on the ends.

This is already fixed in 2.0, do we really want to change the output in 1.5.4 ?

2.0.0 is good, 1.5 we don't care in this case.
