Exclude text file rules for v7.7a:

  The file 'hexedit.exd' contains the file exclusion list for multifile
  loads.

  Any number of filenames to be excluded can be specified. Filenames to be
  excluded may contain wildcard characters ? and *. The ? character matchs
  any single character. The * character matches remaining ones in the
  filename until the character after the * is found.

  Examples:

    *.com
    edit????.txt

  Any * character followed by another * or followed by a ? simply skips
  to the next matching character.

  The exclusion specification may include a character specified not to match
  the filename if preceded with the ^ character. For example:

    file^1.ext

  excludes files without the matching 1 in the filename. In this example
  the files file2.ext, file3.ext would be excluded, but the file file1.ext
  would not.

  The * global character followed by the ^ match character searches the
  remaining filename for the unmatched character. For example, *^z
  would copy all files containing the z character, excluding only files
  without the z character in their filenames. Since the filename is
  searched until the z is found or not, adding any specification after
  the combination *^ is useless, for example, *^z.ext would not
  search for .ext.

  Other specifications, such as, ^*, or ^? are ignored because the
  filename cannot include a * or ?.

  If the source filename contains a ^ character then the exclude
  specification containing a ^ for replacement will not match. For example,
  trying to match file^.ext to file 'file^.ext'. Use file?.ext instead.

  Also, ^^ would work, such as, ^^.* but not if the filename itself
  contained ^^ like 'file^^1.ext'
