i know -)
actually i had this for some time (and in font-ini.tex there is still the
leftover:)
% safer but sometimes introducing newlines in the log
%
% \batchmode
% \font\lastloadedfont\fontfile\somefontspec\relax
% \errorstopmode
% \edef\lastfontname{\fontname\lastloadedfont}%
% \ifx\lastfontname\nullfontname
% \showmessage{\m!fonts}{10}{\fontfile}%
% \expandafter\font\csname#1\endcsname=\defaultfontfile\somefontspec\relax
% \else
% \expandafter\let\csname#1\endcsname\lastloadedfont
% \fi
as commented: newlines in th elog, and i hate an ungly log
a pitty that a decent test didn't make it into etex
