Bug#717621: lintian: apache2 AllowOverride matches obsolete Allow directive check

["Jean-Michel Vourgère" <jmv_deb@nirgal.com>]

Control: tags -1 +patch

Attached is a patch:

It will check there is a white space type character, or a new line, after.

It will also check the directive is a the begining of a line, and will now
ignore comments and the name of a directive in a text, a url, and so on.

Note that all this space is out of $1, so that output is clean.
