Bug #9186 Ready for Commands prompt inside comment blocks

Description:
The reason why I'm classifying this thing as S3 is that the manual reads that "the mysql> prompt indicates that MySQL is ready for a new command".
When you issue a comment in the command line client starting with the /* statement, every following line starts with the mysql> prompt, which is incorrect.
MySQL in not ready for commands, at least as much as it isn't when you're typing a string or naming a field (which corrrectly causes '> and `> prompt to appear)..

This is a bit confusing if you copy a long script and paste in the client to test it.... 

How to repeat:
open a command line client and paste the following commands:

mysql> /*
mysql>
mysql>
mysql> select current_user();
mysql>
mysql>
mysql> */
mysql> select current_user();
+----------------+
| current_user() |
+----------------+
| root@%         |
+----------------+
1 row in set (0.00 sec)

mysql>

Suggested fix:
Create a new prompt to take in account that a comment block closure is pending.
