i was told that there was nothing worth keeping in systems/pdftex,
which is why i moved the whole thing to obsolete/

i note that tetex, at least, doesn't carry protcode.tex (does
miktex?), so in effect protcode.tex can be regarded as "not
represented on ctan".  anyone got any suggestions as to where we
should put felix's mended version, to represent a "current copy"?
