Description:
If I run mysqldump with option WHERE, but put part of it on new line resulting output would be invalid SQL:

./bin/mysqldump -uroot -S /tmp/sveta56.sock --where="\
> user='root'" mysql user

...
--
-- Dumping data for table `user`
--
-- WHERE:  
user=root

How to repeat:
./bin/mysqldump -uroot -S /tmp/sveta56.sock --where="\
> user='root'" mysql user

Suggested fix:
Comment parts of WHERE clause even if they are on the new line
