Motivation for this change
There have been several requests for XOR and XNOR gates to allow more than 2 inputs [#376] [1] [2]. This PR fixes that and updates the docs.
As far as I can see, the previous concern was a potentially ambiguous IEC symbol [ = 1 ]. However, extended gates are widely interpreted to represent the cascade of such binary operations and there is clear demand to display such symbols (from me too).
As a weird quirk, ICE XNOR gates have always been able to accept more than 2 inputs - in opposition to the docs.
Fixes #376
