When I perform svn commands such as the one below I am prompted for my password.  It then gives the option of saving that password as below.  Is it alright to store the password unencrypted?

cs520stu15@cs3:~$ svn ls svn://cs3.calstatela.edu/cs520/s12/cs520stu15/csns2/
Authentication realm: <svn://cs3.calstatela.edu:3690> cs520stu15's repository, s12
Password for 'cs520stu15':

-----------------------------------------------------------------------
ATTENTION!  Your password for authentication realm:

   <svn://cs3.calstatela.edu:3690> cs520stu15's repository, s12

can only be stored to disk unencrypted!  You are advised to configure
your system so that Subversion can store passwords encrypted, if
possible.  See the documentation for details.

You can avoid future appearances of this warning by setting the value
of the 'store-plaintext-passwords' option to either 'yes' or 'no' in
'/home/cs520stu15/.subversion/servers'.
