'\r <database>' mysql syntax is broken

[jason.axley]

>Description:
Trying to connect to a different database with '\r <database>' from the mysql
command-line tool is broken (and has been for a couple mysql releases).

Example:
mysql> \r mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Connection id:    108
Current database: mysql

    ->
^^^^^^^
You'll notice that the mysql program has not gone to the mysql> prompt but
is waiting for further input from the user.  This does _not_ happen if you
use 'connect <database>'.  You can get back to the prompt by entering a
semicolon (;) and hitting enter (you'll get an error:

    -> ;
ERROR 1064: You have an error in your SQL syntax near 'mysql
;' at line 1

but at least you'll get to a prompt).  This also happens on the linux version.

>How-To-Repeat:
	Try to use \r to connect to a specific database by name and it will
	work every time.
>Fix:
	Don't use the '\r <database>' syntax--instead, use 'connect <database>'
	as a work-around.
