Bug#114518: apt-cache showpkg breaks RFC822 conventions

[Bear Giles <bear@coyotesong.com>]

Package: apt
Version: 0.3.19

"apt-cache showpkg" breaks RFC822 conventions on several fields.

A specific example follows - the lines following "Dependencies:"
and "Provides:" are continuation lines that should be indented
by at least one whitespace character.  This breaks any code that
assumes RFC822 output, although a partial workaround is to assume
that any line starting with a digit is a continuation line.

(A minor nit: the example also shows a trailing comma on the
"Versions:" field.  It's not clear if that is significant, or
just an artifact of the processing code.)
