title: Emacs filesets: how to run other (elisp, not shell) commands?
body: <p>There are 5 Elisp commands that can be run on an Emacs fileset, plus the ability to run any shell command. What about all the other Emacs commands? Just to give one example, it would be nice to be able to run M-x occur on a fileset. </p>
  
  <p>I know its possible to mark several files in dired and then run any Emacs command on them (is that true, or am I confused with shell commands?), but it would be very convenient to define a fileset once and then be able to use it like one single file for all kinds of text editing. </p>
  
  <p>Thanks for any advice</p>
