Improve psql's tabular display of wrapped-around data by inserting markers

Browse Source 
in the formerly-always-blank columns just to left and right of the data.
Different marking is used for a line break caused by a newline in the data
than for a straight wraparound.  A newline break is signaled by a "+" in the
right margin column in ASCII mode, or a carriage return arrow in UNICODE mode.
Wraparound is signaled by a dot in the right margin as well as the following
left margin in ASCII mode, or an ellipsis symbol in the same places in UNICODE
mode.  "\pset linestyle old-ascii" is added to make the previous behavior
available if anyone really wants it.

In passing, this commit also cleans up a few regression test files that
had unintended spacing differences from the current actual output.
