Re: Please install: Some improvements to doc-view.el

[Richard Stallman]

      So I think that the
    problem with that was that calling external programs (which might not be
    available) is generally not a good idea.

Is it just a matter that they may not be available?  Or is it also risky?

                                              Since `doc-view' is an emacs
    command and the user is asked if he wants to view the document with
    `doc-view' instead of `view-file', I think my change is safe.

If I understand correctly, `doc-view' also works by calling an
external program.  Why don't the same arguments apply?
