Bug#782559: apt-get complains about unknown options when it's the command that's wrong

[Sam Hardwick <sam.hardwick@iki.fi>]

Package: apt
Version: 1.0.9.7
Severity: minor

Dear Maintainer,

apt-get seems to be parsing commandline arguments incorrectly. For example,
to

"apt-get --purge autoremvoe"

it replies:

"E: Command line option --purge is not understood"

When the expected behaviour would be to complain about the command. This is
only a typo, but could be rather confusing to a user who doesn't understand
what he's doing wrong.
