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.

The '--backup' option would previously accept arguments separated from the
option either by a space or an equals sign. The GNU implementation strictly
requires an "equals" for argument separation.
As the argument to '--backup' is optional, the equals sign mustn't be ommited
as otherwise there is no way to tell a file argument apart from an argument
that's meant for the '--backup' option. This ensures that if '--backup' is
present it either has no further associated arguments (i.e. fallback to the
default), or the arguments are separated by an equals sign.
