Review: psql-wrap-formatting/Unicode UTF-8 table formatting for psql text output

Overview:
Patch to make data output that includes newlines & wrapped lines
consistent with the headers for that data.
Link: https://commitfest.postgresql.org/action/patch_view?id=220

Submission review:
* is in context diff
* applies cleanly to current HEAD
* includes its own test .sql file to verify new output
* includes appropriate doc patches

Usability review:
* the patch does indeed do what it says
* maintains backward compatibility, should the end-user desire it
* included tests perform as advertised

Coding review:
* looks good to me
* fits in with the surrounding code
* no compiler warnings, no crashes
* complete & understandable docs

Personally, I think this rocks. It really improves the readability of
query output.
