Here's another strategy for handling this, inspired by org-protocol[1].
For those who haven't used it, org-protocol invokes emacsclient with an 
"org-protocol://..." URL to let you do things like capture text from 
another application.

Extending from that, what if Emacs introduced URL handlers, so that these:

  emacs mailto:foo <at> bar.com
  emacsclient mailto:foo <at> bar.com

would look up a "mailto:" handler defined somewhere in Emacs[2] (e.g. 
'message-mailto') and call that function instead of 'find-file'. This is 
roughly how the org-protocol module handles this, although it only works 
for emacsclient (it adds advice to a few functions from server.el).

This would be less flexible than having a generic way of feeding certain 
command-line arguments to an Emacs Lisp function, but I'm not sure what 
practical uses we'd need that for aside from handling URLs, as in this 
bug or for org-protocol. If there are some other uses people have for 
the more-flexible implementation, I think it would help to list those so 
we can be sure the chosen solution addresses them.
