In short, (1) ``octal escape \057'' doesn't have special meaning in
Bash glob patterns.  `[\057]' means just one of a literal backslash or
digits 0, 5, or 7.  (2) You need to set `shopt -s extglob` to use
extended glob patterns like `+(...)' and `*(...)'.  Please look at the
paragraph above the list of extended patterns in the manual.
