So it's merely the knowledge of having exported this object already that we
need to know in order to elide re-exporting it.

This code is still 64bit unsafe, as the nPictureId has to be a unique
32bit value for each object, so using the pointer as the key is
horribly dubious, but this should be the same as the original code.

This requires setting a rich comparison flag in Python 2, while Python 3
uses rich comparison by default.

We can't assume that when setting properties whose semantics we don't

This adds the argument -f (--filenames-only), which only prints the
filenames of files containing German comments.
I personally scan the whole file for German strings anyway, as we do
not find German strings with less than 4 chars. So there's not so
much use in printing the found strings.

This option is useful for Intel AppUp builds. On the other hand,
unused STARTCENTER_LAYOUT_STYLE option was removed.

ISCHECKFORPRODUCTUPDATES is a de-facto standard for enabling or
disabling Online Update feature. We had this property but it was
unused for a long time. Now LibreOffice can be installed with
msiexec /i LibO<version>.msi ISCHECKFORPRODUCTUPDATES=0 in order
to disable Online Update feature.
