Hi all,

I'm suggesting adding the Gemini protocol to the regexp for
"buttonizing" URLs. Gemini is a new text-based web protocol (like
gopher) with rising popularity and at least one Emacs package for
browsing (Elpher). URLs are of the form gemini://my.home.page/. Having
Emacs identify these links is useful and all determined by a single
variable. Attached is the patch. For more information about Gemini, here
is a quick introduction:

Best,
