> help: hide command line options marked as "advanced"

> Previously, we have keywords like "(DEPRECATED)" and "(EXPERIMENTAL)" to
> hide command line options in non-verbose help output.

> However, sometimes an option is neither deprecated nor experimental. It's
> well-tested and working, but just not designed to average users. This patch
> adds a keyword "(ADVANCED)" to fit in such use cases.

> Thanks rom1dep for the suggestion of the word "advanced".

I noticed "# i18n:" has special meaning and the change is wrong. I will mark
this as "Superseded" and send a V2.

I will change "is" to "are" as well.
