Adding "found" might seem minor but I feel it has a slight softening on the message. It also maintains scanability as it is at the end and short. As this is a one-off message change and not a styling issue to be consistent with, I think this is safe to put in a patch release.

This requires enabling the [derive feature flag][crate::_features].
You can use -- to escape further arguments.
Let's see what this looks like in the help:
$ escaped-positional-derive --help
A simple to use, efficient, and full-featured Command Line Argument Parser
Usage: escaped-positional-derive[EXE] [OPTIONS] [-- <SLOP>...]
Arguments:
[SLOP]...
Options:
-f
-p <PEAR>
-h, --help Print help
-V, --version Print version
Here is a baseline without any arguments:
$ escaped-positional-derive
-f used: false
-p's value: None
'slops' values: []
Notice that we can't pass positional arguments before --:
$ escaped-positional-derive foo bar
? failed
error: unexpected argument 'foo' found
Usage: escaped-positional-derive[EXE] [OPTIONS] [-- <SLOP>...]
For more information, try '--help'.
But you can after:
$ escaped-positional-derive -f -p=bob -- sloppy slop slop
-f used: true
-p's value: Some("bob")
'slops' values: ["sloppy", "slop", "slop"]
As mentioned, the parser will directly pass everything through:
$ escaped-positional-derive -- -f -p=bob sloppy slop slop
-f used: false
-p's value: None
'slops' values: ["-f", "-p=bob", "sloppy", "slop", "slop"]
