`cut` on empty string returns unexpected result

[mennopruijssers]

when using cut on an empty string, the value you want to strip is removed.

Imagine you want to cut dashes from an input string:

cut value "-"

If value is "2019-12-30" the output will be "20191230"
However, if value is an empty string ("") the output is "-".

This seems the opposite of what I would expect based on the description:

Removes all values of arg from the given string.
