fix: Allow config flag to take a parameter

[MichaelCurrin]

fixes #95

Resolves the error that appears like this without the fix.

docsify start . --config ssr.config.js

Unexpected argument: ./ssr.config.js

Based on tutorial: https://docsify.js.org/#/ssr

[anikethsaha]

can you share link to docs for this ?

may be I missed something

[MichaelCurrin]

The start command is missing from these docs.

• https://github.com/docsifyjs/docsify-cli/blob/master/README.md#usage
• https://github.com/docsifyjs/docsify-cli/blob/master/docs/README.md#usage

The command is defined here.

docsify-cli/lib/cli.js

Line 89 in 9b35260

command: 'start <path>',

This is what I see locally when reading the help:

sorry for not being clear.

by docs , I meant docs of yargs

[MichaelCurrin]

Example:

docsify start . --config ssr.config.js --port 5000

port requires a number and accepts 1 argument.

config requires a string and so needs 1 argument, despite the code saying it needs zero.

If you leave off the value for --config, you don't get an error as "Unexpected argument: ./ssr.config.js. Since the default for config is false`, setting the flag and not giving an argument is the same as not using the flag at all, as far as I can see.
