Regression in error messages when two args from a non-multiple group were passed #1859
Description
This is what it used to look like:
error: The argument '--delete' cannot be used with '<base>'
USAGE:
clap-test <base|--delete>
For more information try --help"
After #1856 has landed, it looks like
error: Found argument '--all' which wasn't expected, or isn't valid in this context
If you tried to supply `--all` as a PATTERN use `-- --all`
USAGE:
clap-test <-a|--delete>
For more information try --help"
This is undesirable and must be corrected, but the bugfix is more important.
