Documented in TIP #496 that -justify can only be honored if there is enough display space, and a bit of reformatting. check-in: 6896b0788d user: fvogel tags: trunk

Changes to tip/421.md.

    49     49   This will iterate internally over the elements of the array called
    50     50   _arrayName_ in array-iteration order \(i.e., the same as that used by the
    51     51   other **array** subcommands\), setting the variable _keyVar_ to the name of
    52     52   the element and the variable _valueVar_ to the content of the element before
    53     53   evaluating the script _body_. The result will be the empty string \(excepting
    54     54   errors, **return**, etc.\) and any contained **break** and **continue**
    55     55   will have their normal interpretation as loop control operations.
           56  +
           57  +Modifying the array while this command is iterating over it will make the
           58  +**array for** command terminate with an error once the current execution of
           59  +_body_ finishes.

    59     63   Branch: `tip-421` (Code is also available
    60     64   [here](https://github.com/flightaware/Tcl-bounties/issues/12) within a
    61     65   comment, but that is _not_ the definitive version.)
