-P CLI argument does not work as expected

• code-server version: Development
• OS Version: MAC OS X 10.13.6

Description

According to code-server --help, this is the expected format for passing a password argument to the CLI:

-P, --password <value> Specify a password for authentication.

Currently, the --password argument works. But -P does not.

Steps to Reproduce

1. Attempt to run code-server with a -P CLI argument

UPDATE: This appears to be a quirk of the commander package we're using for the CLI. All arguments that are set using a single dash and require CLI input cannot handle = symbols. E.G

code-server -P abcdefg  (This works)
code-server -P=abcdefg (This throws errors)

Which is a bit odd because

code-server --password abcdegf (works)
code-server --password=abcdegf (also works)

This quirk is consistent and repeatable with the -h (for host) and -p (for port) flags as well.
