Subject: [PATCH] Fix a bug introduced by DEFAULTS feature.  When the config
 file doesn't exist, we make a directory and then say "oops, that file isn't
 there" leaving the directory behind.  Add a stat for the config file so that
 we detect this before making the directory.  This is semi-lame, but less lame
 than having this bug.
