If a directory was reported with a concrete status by git, it was
assumed that all files below this directory would have the same status.
This is not the case were git ignore files are applied to some files
in subdirectories.
Fixes#461.
Showing a report for every argument given on the command line
is not suitable when using wildcards and did not work with `--tree`.
Also, it was only designed to work with directories given as
arguments.
```
lib/colorls/core.rb:213:14: C: Style/RedundantArgument: Argument ' ' is
redundant because it is implied by default.
size = Filesize.from("#{filesize} B").pretty.split(' ')

Some Unicode characters, e.g. chinese, consume more space when displayed on a terminal
than a single roman character. To avoid alignment issues, try to determine the width
using the unicode-display_width gem.
* delete `#remove` method
* remove `#delete_prefix` spec, it was only used for Ruby < 2.5 (see 86cfa2f5cf)
* add specifications for `#colorize` and `#uniq`
On Windows, MRI Ruby uses the `FindFirstFileW` et. al. kind of functions with
wide character paths and constantly converts from multi-byte to wide character
encoding back and forth when calling any methods on `File` or `Dir`.
This means that when using `Encoding::ASCII_8BIT` for reading directory entries,
that this does not round trip properly, if a file name contains unicode
characters. That is because Ruby assumes the path string is encoded in Windows
Codepage 1252[1].
* skip symlink test if files were checked out from git as textual symlinks on
Windows
* use UTF-8 encoding on Windows, since this properly round-trips between
multi-byte and wide character encoding
* travis: windows job no longer is allowed to fail

A *file* is assigned a generic icon / glyph in `files.yaml`, so looking up
`:file` in the corresponding hash always succeeds, but `:file` is also used as
the fallback key if a file's extension is not recognized.
First determining the color and group of a given file before falling back to
the `:file` key fixes this issue.
