Updates to the "wb" tool

["Adam D. Barratt" <adam@adam-barratt.org.uk>]

Hi,

I've just pushed a few changes to the "wb" tool:

* The expansion of "ALL" in architecture lists is now distribution
specific and includes all architectures for the given distribution; this
means that for unstable it now includes hurd-i386.

* A distribution name may now be specified inline, using the syntax:

  command PKGS . ARCHES [ . DIST ] [ . OPTIONS ]

The existing syntax for specifying a distribution name, using "-d dist",
is  still supported but the two syntaxes may not be mixed within a
single instruction.

* The tool now maps the etch, lenny, squeeze and sid codenames to the
corresponding distribution name.

Cheers,

Adam
