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.
* Style/MultilineWhenThen: Do not use then for multiline when statement
* Style/StringConcatenation: Prefer string interpolation to string concatenation
* Style/OptionalBooleanParameter: Use keyword arguments when defining method with boolean argument
* Style/GlobalStdStream: Use $stderr instead of STDERR
* Style/GlobalStdStream: Use $stdout instead of STDOUT
When trying to `require` a gem running in an unlinked directory, an exception is
thrown because `Dir.pwd` is called (see rubygems/rubygems#3087).
Until the fix lands in an official release, we monkey patch `Dir.pwd` to return
'/' if a `Errno::ENOENT` exception is raised while loading the colorls gem.
This should work for all Unixes. On Windows, this error cannot happen since you
cannot unlink a directory which is still in use by a process.
Fixes#351.
