Typo in variable name 'subersion_cron_fetch_amount'

subversion_fetch_repository() loads this variable for determining the limit, but won't be very successful with it as the variable name misses the 'v' in 'subversion'. Snippet:

   $cmd = array(
      escapeshellarg(escapeshellcmd(variable_get('subversion_svn_binary', '/usr/bin/svn'))),
      'log',
      '-r', ($start_revision > 0 ? $start_revision+1 : 0) . ":HEAD",
      '--incremental',
      '--non-interactive',
      '--xml',
      '-v',
      '--limit', variable_get('subersion_cron_fetch_amount', 100),
   );

It's in the line with '--limit', currently line 1999.
