git ls-files used to error out if given paths which point outside the current
working directory, such as '../'. We now allow such paths and the output is
analogous to git grep -l.

There are two changes with respect to the previous version of this
patch.
- write_name() now uses the new write_name_quoted_relative()
- prefix_offset is renamed to prefix_len, which is much more
intuitive
