Fix autoinfo for "set-option -remove" not showing option-specific info

Browse Source 
On a command prompt like

	"set-option -remove buffer aligntab "

we fail to show the aligntab-specific info . Fix this by skipping a
leading -remove, just like we skip -add.

Add an explicit specialization of contains() because otherwise I'd
need to write something like

	contains(Array{"-add", "remove"}, param)
