Description:
I have created a database with name ';havesinglequotes' (single quote at begin and end + a semicolon in it) with one table tb1.

For taking backup I ran the mysqldump with below arguments:

mysqldump --single-transaction --flush-logs --master-data=2 --create-options --default-character-set=utf8 --routines -u root --socket=/tmp/mysql.sock "';havesinglequotes'" -p 

The command fails while dumping routines. Complete output pasted below:

mysqldump --flush-logs --master-data=2 --create-options -B --default-character-set=utf8 --routines -u root --socket=/tmp/mysql.sock "';havesinglequotes'" -p

mysqldump version:
./bin/mysqldump -V
mysqldump  Ver 10.13 Distrib 5.5.27, for linux2.6 (x86_64)
Server version: 5.5.27-log MySQL Community Server (GPL)

How to repeat:

steps:
#1. create database `';havesinglequotes'`;

#2. use `';havesinglequotes'`;

#3.create a table tb1 of any arguments.

I created a table tb1 like below:
create table tb1(i int); and insert few rows

#4.Try to dump the database with routines. (Though the routines are not created here)
mysqldump --flush-logs --master-data=2 --create-options -B --default-character-set=utf8 --routines -u root --socket=/tmp/mysql.sock "';havesinglequotes'" -p 

#5. It will fail with below error:

-- 
-- Dumping routines for database '';havesinglequotes'' 
-- 
mysqldump: Couldn't execute 'use `\';havesinglequotes\'`': Unknown database '\';havesinglequotes\'' (1049)
