Well, perhaps.  I'm just not sure it's the right thing to do it at
postinstall time.  I mean, it's not impossible, obviously, but it's
a lot of stuff per executable and running this for a few thousand .exe
files could take some time.

We would also have to make sure that the sections with long section
names are recreated after adding the .rsrc section, which is something
I don't quite see how to accomplish, right now.
