Answering late on this message.

You may see description of:

(defvar goto-address-uri-schemes
  ;; We use `thing-at-point-uri-schemes', with a few exclusions,
  ;; as listed in `goto-address-uri-schemes-ignored'.

thing-at-point-uri-schemes ⇒ ("aaa://" "about:" "acap://" "apt:" "bzr://" 
"bzr+ssh://" "attachment:/" "chrome://" "cid:" "content://" "crid://" "cvs://" 
"data:" "dav:" "dict://" "doi:" "dns:" "dtn:" "feed:" "file:/" "finger://" 
"fish://" "ftp://"; "geo:" "git://" "go:" "gopher://"; "h323:" "http://"; 
"https://"; "im:" "imap://" "info:" "ipp:" "irc://" "irc6://" "ircs://" 
"iris.beep:" "jar:" "ldap://"; "ldaps://" "magnet:" "mailto:"; "mid:" "mtqp://" 
"mupdate://" "news:"; "nfs://" "nntp://"; "opaquelocktoken:" "pop://" "pres:" 
"resource://" "rmi://" "rsync://" "rtsp://" "rtspu://" "service:" "sftp://"; 
"sip:" "sips:" "smb://" "sms:" "snmp://" "soap.beep://" "soap.beeps://" 
"ssh://" "svn://" "svn+ssh://" "tag:" "tel:" "telnet://" "tftp://"; "tip://" 
"tn3270://" "udp://" "urn:" "uuid:" "vemmi://" "webcal://" "xri://" 
"xmlrpc.beep://" "xmlrpc.beeps://" "z39.50r://" "z39.50s://" "xmpp:" "fax:" 
"man:" "mms://" "mmsh://" "modem:" "prospero:" "snews:"; "wais://")

And then see:

browse-url-handlers is a variable defined in ‘browse-url.el’.

Its value is
(("gemini:" . elpher-go)
 ("gopher:" . elpher-handler-go)
 ("about:" . hyperscope-about)
 ("hyperscope:" . hyperscope-go)
 ("e2dk://" . amule-handler))
Original value was nil

So now, IMHO, Hyperbole should automatically know how to open such
various uncommon hyperlinks if browse-url-handlers has been defined.
