  26
  27     Search for a specific trigger method in a array of trigger methods (check
  28     if either 'command' or 'method' matches).
  29
  30     INPUTS
  31
  32     methods  --  array of trigger methods; may be NULL
  33     command  --  name of trigger method (may be NULL; if so, 'command'
  34                         is not matched against)
  35     method   --  id of trigger method to search for (may be ~0; if so, don't
  36                  match against 'method'.
  37
  38     RESULT
  39
  40     Pointer to trigger method table entry (struct DTMethod *) or NULL if the
  41     method wasn't found.
