Comment 79 for bug 25830

As Comment #55 states the RFC:

>such an action might be
>reasonable for unrecognized subtypes of text, but not for
>unrecognized subtypes of image or audio.

It says _might_ be reasonable, not should. If I try to download a
text/almost-binary-whatever (such as /etc/sendmail.cf), I expect a dialog asking
what to do:

You are trying to view text/almost-binary-whatever content...
() Save to disk...
() Show in browser as text/plain
() Open with program...
 [x] Always do the same for this type
      [OK] [Cancel]

Just my 2 yen...
