## Message

```
breaking: Add positional, precision and width support to std.fmt

This removes the odd width and precision specifiers found and replacing
them with the more consistent api described in #1358.

Take the following example:

    {1:5.9}

This refers to the first argument (0-indexed) in the argument list. It
will be printed with a minimum width of 5 and will have a precision of 9
(if applicable).

Not all types correctly use these parameters just yet. There are still
some missing gaps to fill in. Fill characters and alignment have yet to
be implemented.

```
