* generic/tclIOCmd.c: Revise [open] so that it interprets leading

        zero strings passed as the "permissions" argument as octal numbers,
        even if Tcl itself no longer parses integers in that way.

        * unix/tclUnixFCmd.c:   Revise the "-permissions" [file attribute] so
        that it interprets leading zero strings as octal numbers, even if Tcl
        itself no longer parses integers in that way.

        * generic/tclCompExpr.c:        Corrections to code that produces
        * generic/tclUtil.c:    extended "bad octal" error messages.

        * tests/cmdAH.test:     Test revisions so that tests pass whether or
        * tests/cmdIL.test:     not Tcl parses leading zero strings as octal.
