Follow-up Comment #14, bug #64061 (project groff):

> True, but I thought you might have a setup that generated an expected temp
file for the fake-pdfinfo input, which you could diff against mine, bypassing
the eyeballs.
Ah, no...that didn't occur to me.
I don't really _want_ to bypass eyeballs. Many brains are better than few.
> Adding an output line to the temp file and groffing it also gives the same
results on both Mac and Gentoo Linux:
Good deal!

> Not that we need _more_ options at this point, since two others now have
working implementations, but I don't think this particular objection has much
weight: the grep wasn't eliminated because it was incurring a noticeable
performance penalty, but because it was deemed unnecessary on code inspection.
I doubt the overhead of two invocations of pdfinfo would make a significant
runtime difference even in a document that included dozens of PDFs.
I think that's fair. The recovered efficiency is more significant in human
brain cycles than CPU clock cycles.
