For ages now, I've been wishing that pdftex output the non-pdf special it complains about finding. Often it's obvious, but sometimes it's not, and why not report it?
Does anyone see a problem with this? All I can imagine is that scripts trying to parse the output might be unhappy. So we can keep the original error message unchanged, exclamation point and all, and just add the special text.
As in something like the below (not tested). Probably better to truncate the special text instead of printing the whole thing, as it could be annoyingly long, but I'm wondering about the general idea.
Wdyt? --thanks, karl.
