Maybe I'm missing something, but I don't understand why support for
file:// protocol is needed in Info.  Info already supports its own
protocol of referencing to an external file, via the @xref command and
its varieties, with 4 or more arguments.  So why cannot you simply use
one of those cross-referencing commands, if you want a reference to
another manual?

Thanks.
