Description:
The mysql client formerly right-justified numeric column
values.  This no longer occurs, making numeric columns
more difficult to understand.

How to repeat:
Test input:

drop table if exists t;
create table t (i int, d decimal(10,2), f float);
insert into t (i,d,f)
values
(1,1,1),
(21,21,21),
(321,321,321),
(4321,4321,4321),
(54321,54321,54321);
select
i as 'integer value',
d as 'decimal value',
f as 'float value'
from t;

Good results in 5.0 before 5.0.19 and in 5.1 before 5.1.8:

+---------------+---------------+-------------+
| integer value | decimal value | float value |
+---------------+---------------+-------------+
|             1 |          1.00 |           1 |
|            21 |         21.00 |          21 |
|           321 |        321.00 |         321 |
|          4321 |       4321.00 |        4321 |
|         54321 |      54321.00 |       54321 |
+---------------+---------------+-------------+

Bad results in 5.0 as of 5.0.19 and in 5.1 as of 5.1.8:

+---------------+---------------+-------------+
| integer value | decimal value | float value |
+---------------+---------------+-------------+
| 1             | 1.00          | 1           |
| 21            | 21.00         | 21          |
| 321           | 321.00        | 321         |
| 4321          | 4321.00       | 4321        |
| 54321         | 54321.00      | 54321       |
+---------------+---------------+-------------+

Suggested fix:
Please restore previous behavior for numeric columns.

Patch looks good to me.

Patch ok for me too.

Patch applies to 5.0.21 and 5.1.10.

There were two bugs here, cause by the same "ASCII-zero" change of a few versions ago:  Not right-justifying numbers and not printing "NULL".  This single patch restores both.

Noted in 5.0.21, 5.1.10 changelogs.

A recent change caused the <command>mysql</command> client not
to display <literal>NULL</literal> values correctly and to
display numeric columns left-justified rather than
right-justified. The problems have been corrected. (Bug #18265)
