I looked at eliminating safe_fname() in favor of putting the filtering
into rwrite(), and there are a bunch of places that expect to be able
to output tabs and newlines as a part of the string.  So, I decided to
try to find all the places that didn't use either safe_fname() or
full_fname() (which calls safe_fname()) and fix them.  I've also checked
in an improvement to safe_fname() that makes it use isprint() (instead
of just looking for newlines).
