[PATCH v2 0/2] builtin/ls-files.c:add git ls-file --dedup option

I am reading the source code of git ls-files and learned that git ls -files
may have duplicate entries when conflict occurs in a branch merge or when
different options are used at the same time. Users may fell confuse when
they see these duplicate entries.

As Junio C Hamano said ,it have odd behaviour.

Therefore, we can provide an additional option to git ls-files to delete
those repeated information.

This fixes https://github.com/gitgitgadget/git/issues/198

Thanks!
