The only other case I am aware of is where a "text" file includes the
sequence \012\001 anywhere in it - this will go horribly wrong.  If
you do this with Sun's SCCS when checking in the first delta (usually
1.1) it will almost always recover by swiching to binary mode.  If
you're not checking in the intiial delta, you can't recover. 

The only case I'm aware of for binary (i.e. Sun-style encoded) files
is where you feed in a binary file to "admin -i" via stdin and it
turns out to be binary but you didn't specify "-fb" on the command
line.

I suspect that you might be able to louse things up by feeding in
\012\001T as part of a delta comment, but I've never tried that.
