Bug#798180: ack-grep: should not strip leading "./" from filenames

[Jakub Wilk]

Package: ack-grep
Version: 2.14-4

When ack prints filenames, it strips leading "./". This is harmful when 
you pass these filenames to another program, because a filename starting 
with "--" might be interpreted as an option:

$ ls
--interactive=.html
$ ack -f --html --print0 ./ | xargs -0 rm -f
rm: invalid argument ‘.html’ for ‘--interactive’
Valid arguments are:
  - ‘never’, ‘no’, ‘none’
  - ‘once’
  - ‘always’, ‘yes’
Try 'rm --help' for more information.
