- use pessimistic version constraints for all dependencies in the gemspec
In a long listing, the user was only shown when owning the file. Originally, the
user was only colorized when owning the file.
Change that to always colorize the user using the defined `:user` color.
Fixes#187.
In the `-z` git status format, a NUL follows each file name. When files are
renamed, the status field is followed by a space, the "to" path, a NUL
character, the "from" path and a terminating NUL.
This fixes#185.
* no longer traverse complete directory trees to determine git status for
directories
* properly report status for folders with changed files
* skip the parent folder since we do not have git status about it
