[Yum] man page question

[R P Herrold]

In the man page for yum, yum-0.9.4-1_8x 

I find:
       -y     Assume yes; assume that the answer to  answer  to  any  question
              which would be asked is yes.  Configuration  Item: assume-yes

Is this actually:
    assume=yes

( "=" not "-" ) ?

I ask because I tried using it:

[root at ftp root]# yum install php-mysql
Traceback (most recent call last):
  File "/usr/bin/yum", line 24, in ?
    yummain.main(sys.argv[1:])
  File "yummain.py", line 104, in main
  File "yummain.py", line 64, in parseCmdArgs
  File "config.py", line 27, in __init__
  File "/usr/lib/python2.2/ConfigParser.py", line 233, in read
    self.__read(fp, filename)
  File "/usr/lib/python2.2/ConfigParser.py", line 474, in __read
    raise e
ConfigParser.ParsingError: File contains parsing errors: 
/etc/yum.conf
        [line  7]: 'assume-yes\n'
[root at ftp root]#

But when I make that change and try an unattended install ...

[root at ftp root]# cat /etc/yum.conf | grep assum
assume=yes
[root at ftp root]# yum install php-mysql

I will do the following:
[install: php-mysql.i386]
Is this ok [y/N]: y

[root at ftp root]#

so that alternative version of the option seems not to work
