   3## applypatch takes four file arguments, and uses those to
   4## apply the unpacked patch (surprise surprise) that they
   5## represent to the current tree.
   6##
   7## The arguments are:
   8##      $1 - file with commit message
   9##      $2 - file with the actual patch
  10##      $3 - "info" file with Author, email and subject
  11##      $4 - optional file containing signoff to add
  12##
  13signoff="$4"
  14final=.dotest/final-commit
  15##
  16## If this file exists, we ask before applying
