In short, I mean something like the attached.  I have named the flag
content_patterns, and switched it to an array so as we can check that
toc.dat is always uncompression and that the other data files are
always uncompressed.

This is slightly more complicated as there is just one file generated
for the compression and non-compression cases, so I have let that as
it is now.
