[PATCH] Add --flatten,-f for better interaction with filters.

[Dimitri Sabadie]

The current mitigation has always been to use various scripts for every
integration, such as dmenu, bemenu, skim, fzf, etc. and it requires
everyone to keep writing the same code. This commit allows to get an
easy-to-consume interface for all filter programs.
