This test is exercised by page 4 of multipage.pdf. If all images are
JPEGs, and one of deskew/clean removes DPI information, make sure that
we can get the right information back and that the DPI stays square.
-Remove Test_Issue_28.pdf (inherited from fritz-hh, source unknown)
-Replace missing_docinfo.pdf (received from user, but it's a printout of
a website; unclear status, so created a new PDF with the same effect)
-Others are okay
fileinput is supposed to save time in these cases but it's not capable
of doing both in-place rewrites and working with a non-ascii encoding.
This was not noticed until characters outside of ASCII were picked up
by tesseract and saved in a HOCR file. Rework some surrounding code as
well and add multilingual test cases.
ruffus swallows the return code if the process of handling an exception
we hit an error in ruffus' own code, which can happen. So pick through
its error stack and find out if there's an interesting return code in
there. Had to use eval() of all things.
Also suppress the stack trace for normal error conditions that don't
need one.
