To "view" pdf files in text consoles, and view their diffs, through `git
diff --textconv` currently I have use the following hand-made ~/.mailcap:

    application/pdf; pdftotext -layout '%s' -; copiousoutput


It would be nice, if poppler-utils provided something like that out of
the box in /usr/lib/mime-info/packages/poppler-utils.


Thanks beforehand,
Kirill
