Triage:	D5 (Feature request)

Description:
This patch adds --auto-vertical-output to the command client. When queries are executed
with \g or ; and this option is enabled the client will switch to vertical mode if the
result set is going to be wider than the terminal. \G forces vertical. 

The patch is available at http://ebergen.net/patches/auto_vertical.patch

How to repeat:
Execute a select with a result wider than the screen and watch it wrap.

Suggested fix:
Apply the patch and set the option in my.cnf :)

Thank you for the patch.

  Bug#26780: automatic vertical output for wide results
  
  Feature from Eric Bergen, CLA signed 2007-06-27.
  
  Adds new mysql client option "--auto-vertical-output", which causes
  the client to test whether a result table is too wide for the current
  window (where available) and emit vertical results in that case. 
  Otherwise, it sends normal tabular results.

Patch looks OK; minor style comment and a few additional tests requested, but no need for
re-review.

This slipped by me unnoticed somehow.  It's been in 6.0 since (probably) November.

The version for this feature is 6.0.4.

Noted in 6.0.4 changelog. Also added option description to mysql section.

Bug#26780: automatic vertical output for wide results

Feature from Eric Bergen, CLA signed 2007-06-27.

Adds new mysql client option "--auto-vertical-output", which causes
the client to test whether a result table is too wide for the current
window (where available) and emit vertical results in that case.
Otherwise, it sends normal tabular results.
@ client/client_priv.h
Add another enum value to client options, for automatic vertical output.
@ client/mysql.cc
Add another command-line option, "auto-vertical-output".

Add functions to get the terminal width and functions to get the widths of fields.

Use them together to emit vertical output when some output table is too wide to
fit in the terminal. If the terminal doesn't support reading its width, then
assume
80-positions wide.
@ mysql-test/r/mysql.result
Show that various select statements do work as expected. Wide tables become
vertical
and narrow ones do not.
@ mysql-test/t/mysql.test
Show that various select statements do work as expected.

These should be suitable for a wide range of window capabilities and sizes. Under
extreme circumstances, the results could be arbitrary.

Backported to 5.6.0  (6.0-codebase revid: 2469.270.2)
