Insufficient permissions error handling

I worked through an issue this morning with a Subversion user that was unable to store a password locally:

Authentication realm: <https://code:443> Zinch SVN Drupal
Password for 'dev':

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

   <https://code:443> SVN

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
'/var/lib/hudson/.subversion/servers'.
-----------------------------------------------------------------------
Store password unencrypted (yes/no)? yes
At revision 2260.

The password wasn't actually being stored, the root of the problem being that auth/svn.simple/* was set read-only/444 (the cause of this is still unknown).

I talked to Stefan (stsp) this morning in #svn and he wants to add better error handling here when the file isn't writable instead of silently failing to store the password. The relevant IRC log is here: http://colabti.org/irclogger/irclogger_log/svn?date=2011-03-03#l243
