The intent is that VFP's become self-contained entities so that
for instance GZIP/GUNZIP and TESTGUNZIP will use their init-> functions
to mangle headers as appropriate.

We're not *quite* there yet, and there is a complication in relation
to how we mangle IMS-fetched objects headers which I have not found
a good solution to yet.

As always: if you spot any wrong behaviour, by all means tell me!
