Cannot watch on specific host

[minhchu]

Problem:

When I run preact watch --host "127.0.0.1" inside a preact project created with preact-cli, I got this screen:

It seems that yargs package overrides the h alias option and turns it into a help command.

How to fix:

Delete the alias of host option resolves the issue.

@minhchu ah, right !!

yargs defaults -h to help.

Traditionally, a --host flag is aliased to -H
