Why foo.pdf exists then? It could still be the source: latex/dvips
doesn't support PDF, thus foo.eps could be the generated file.

No. The explicit extension always triggers its rule.
Differences happens by the extension search order, if no extension
is given. Then the file that is found first triggers the rule,
choosen by the file's extension.

If someone uses EPS files as original files. And there are some
PDF files that should be ignored, then setting
