The custom usage string does not have to include the "sort\nUsage:" part,
because this part is already printed by clap.
It prevents the following duplication:
USAGE:
sort
Usage:
sort [OPTION]... [FILE]..
Now, only the following is printed:
USAGE:
sort [OPTION]... [FILE]...
The `uname` `-o` switch reports the operating system used. If the GNU C
standard library (glibc) is not in use, for example if musl is being
used instead, report "Linux" instead of "GNU/Linux".

This makes clap wrap the help text according to the terminal width,
which improves readability for terminal widths < 120 chars,
because clap defaults to a width of 120 chars without this feature.
This reimplements version_cmp, which is used in sort and ls to sort
according to versions.
However, it is not bug-for-bug identical with GNU's implementation.
I reported a bug with GNU here:
https://lists.gnu.org/archive/html/bug-coreutils/2021-06/msg00045.html
This implementation does not contain the bugs regarding the handling of
file extensions and null bytes.
Adds the ability to perform file backups before installing newer files on top
of existing ones. Adds a status message about backups to stdout if running in
verbose mode.
