Option with three or more trailing hyphens parsed as positional argument

[0x2b3bfa0]

Description

[email protected] and later versions interpret options with three or more trailing hyphens as positional parameters. This issue only happens when options and values are separated with an equal sign.

Actual behavior

> require('yargs-parser')(["--option=---"])
{ _: [ '--option=---' ] }

Desired behavior

> require('yargs-parser')(["--option=---"])
{ _: [], option: '---' }
