I don't know how user protocols work.  But if you define a
protocol that runs arbitrary shell commands, you enable attacks
where a malicious web page runs such a command, pretending to get
a style sheet from the output.  So I advise against defining such
risky protocols until ELinks gets a way to disable a link based
on its source.

Instead, you could define a "goto-url" hook, as ELinks does not
call that when following a link from a document.  (There is a
separate "follow-url" hook that is called for those.)
