hm - but when you write e.g.
\pdffontexpand\tenrm 30 20 10 1000
then pdftex will show this font as /cmr10/ instead of \tenrm and this
will not add any pdftex-specific info, so i see no need of changing
standard TeX's behavior.
also, with \pdffontexpand, the stretch/shrink/step/expand values are
bound to the font macro, in the above example, to \tenrm, so if we see
\tenrm we have exactly the same info as when we'll see /cmr10/
that's why i think that it's better to revert to compatibility with
maybe it will make sense to add a new integer primitive which will be
a flag of whether to show the actual values of expansion selected for
fonts, e.g. if \pdftracefontnames=1, pdftex will show
"\tenrm(expanded 10) " instead of "\tenrm ".
but if \pdftracefontnames=0, standard TeX-style font names will be
also, when \pdftracefontnames=1, pdftex may change the way it shows
the \meaning\tenrm (or the same as \show\tenrm): instead of expanding
to "select font cmr10", pdftex can add "select font cmr10 stretch 30
shrink 20 step 10 expand 1000" or something like that.
