[pdftex] font names in over/underfull box messages

[Vladimir Volovich]

Hi,

i noticed that pdftex produces different output than standard TeX in
over/underfull box messages, namely the font names look differently:

1) here's the output of TeX:

> $ tex \\relax
> This is TeX, Version 3.14159 (Web2C 7.3.9)
>
> *\showhyphens{hyphenation}
>
> Underfull \hbox (badness 10000) detected at line 0
> [] \tenrm hy-phen-ation


2) here's the output of pdfTeX:

> $ pdftex \\relax
> This is pdfTeX, Version 3.14159-1.10a-devel (Web2C 7.3.9)
> {/opt/local/teTeX/share/texmf/pdftex/config/pdftex.cfg}
> *\showhyphens{hyphenation}
>
> Underfull \hbox (badness 10000) detected at line 0
> [] /cmr10/hy-phen-ation

Note that TeX prints font macro name (e.g. "\tenrm ") while pdftex
prints font name delimited with slashes (in this case "/cmr10/")

This is very confusing, - why such a change to pdftex was made?
It looks like a very non-standard behavior, and it makes the overfull
messages harder to read (and maybe it also makes pdftex incompatible
with TeX WRT trip test).

Best,
v.
