There already is a 'multiple file' type for the file options, where you 
could do something like '-f 1.xtc 2.xtc 3.xtc' or '-f 1.xtc -o out.xvg 
-f 2.xtc'. It is currently probably only used by trjcat and eneconv, but 
it should be straightforward to use it in other tools. We'd need library 
functions to handle multiple inputs as well, currently, IIRC, trjcat and 
eneconv handle this internally.
