Log:
  mergemaster: Avoid "/var/tmp/temproot disappeared" if there is nothing to
  compare.
  
  Because of the change to find in SVN r253886, the entire temproot would be
  deleted if it became empty, leading to a confusing message "*** FATAL ERROR:
  The temproot directory ${TEMPROOT} has disappeared!"
  
  Note that mergemaster does not do anything useful in this situation anyway
  (e.g. put IGNORE_FILES="/etc/group /etc/master.passwd" in
  /etc/mergemaster.rc and run mergemaster -p).
  
  As noted in that commit, add -mindepth 1.
