* Implemented --indicator-style flag on ls.
* Rust fmt
* Grouped indicator_style args.
* Added tests for sockets and pipes.
Needed to modify util.rs to add support for pipes (aka FIFOs).
* Updated util.rs to remove FIFO operations on Windows
* Fixed slight error in specifying (not(windows))
* Fixed style violations and added indicator_style test for non-unix systems
* install: implement `-C` / `--compare`
GNU coreutils [1] checks the following: whether
- either file is nonexistent,
- there's a sticky bit or set[ug]id bit in play,
- either file isn't a regular file,
- the sizes of both files mismatch,
- the destination file's owner differs from intended, or
- the contents of both files mismatch.

* Add test: non-regular files
* Forgot a #[test]
* Give up on non-regular file test
* `cargo fmt` install.rs
- refactor internal version specifications to be ">=M.m.p" (where M.m.p is *already published*)
## [why]
Loosening internal version dependencies decreases the coupling between packages such
that packages can be published in a looser order. It allows the packages to be version
updated and published in tandem (ie, by using `cargo workspace ...`). Once published,
the internal versions can then be updated (again, to an *already published* package
version), as needed.
- imported crate name collisions bypass implemented
## [why]
There may be some core or external crates required/used by this project that collide with
uutil names. For example, the `test` util collides with the rust core crate 'test' which
is used behind the scenes for testing. Without the renaming scheme used here, cryptic and
fatal compiler errors occur when compiling the integration tests.
## [why]
'textwrap' is currently unstable, with "term_size" being an undocumented, but required,
feature. The feature name has already changed within the repository 'master' branch.
But that branch has never been pushed to a new version.
Pin for now with "!maint" mark and comment.
- final multi-binary will now function correctly with any binary/executable name
- multi-binary container acts as the specified util IF EITHER ...
1. the binary/executable name exactly matches the name of an applet/util
2. the binary/exectuable name matches <PREFIX><UTIL_NAME> pattern
* where the PREFIX is any string ending in a non-alphanumeric character
