. fixed bug: the -d test at (previous) line 179 was failing in cases
  where the directory entry being tested wasn't in the current
  directory and the argument to -d wasn't the path from the current
  directory.  That is, "-d $entry" became "-d $fullpath".
. added code affecting how filenames are displayed in output.  in
  addition to the previous (and maintained) practice of printing
  non-printable characters as backslashes followed by three digit
  octal numbers:
  . each backslash will be printed as two backslashes
  . each space     will be printed as "\ "
  . each tab       will be printed as "\t"
  . each newline   will be printed as "\n"
