Add documentation for the `--foo[=<bar>]` syntax

Question

If you want to provide a flag that can optionally include a value, the syntax is --foo[=<bar>].

If you want to make that flag with an optional value entirely optional as well, the syntax is [--foo[=<bar>]].

This needs to be documented in the command cookbook.

I thought it's [--foo[=<bar>]] 🙂

Edit: never mind...need more coffee.

@swissspidy Adapted the description to include both.
