Description:
For tabular output format, the mysql client displays an extra space at the end of result set lines that display data rows. This is, in one sense, merely a cosmetic problem. However, it has a practical implication in that it does not occur in older versions, so the extra spaces make diffing output between old and new versions more difficult: The extra spaces are spurious because they cause diff to find differences that aren't "real".

How to repeat:
The problem affects MySQL 5.0 and up. It does not affect MySQL 4.1. I use cat -E to display $ at the ends of output lines.

~% /var/mysql/40124/bin/mysql -t -e 'select 1' |cat -E
+---+$
| 1 |$
+---+$
| 1 |$

~% /var/mysql/50046/bin/mysql -t -e 'select 1' | cat -E
+---+$

| 1 | $

~% /var/mysql/50121/bin/mysql -t -e 'select 1' | cat -E
