It is not a great problem to use make-process:

I think that at least a :sentinel should be added to improve error 
reporting. The code just before these lines has another problem (I hope 
it is really rare):

I would avoid shell since direct execution of the handler should be more 
robust, e.g. quoting of arguments is not necessary. Unfortunately RFC on 
mailcap states that command is executed by shell. On the other hand only 
a few of viewer entries have commands that could not be handled without 
shell.
