Ah ok, up to the listing of the packages being updated that is fine.
So what you need is something like
	end-of-header
after the update block, like
	end-of-updates
because everything below is the postinst actions taken by tlmgr.

Would it be enough to have the line
	end-of-updates
on a line itself?

No. the tlmgr:package log stuff should actually be on STDERR, did you
check that?

Can you run the above with 2>/dev/null to see what is written to stdout?

Of course it could be that some messages are still "print"-ed, and not
using our own "info" routine which in the case of machine-readable 
outputs to STDERR.

So let me know what you need, either a end-of-updates, or fixing some
spurious output to STDOUT. I think at the time we discussed and implemented
that the idea was to redirect (within tlmgr) all output that is not
in machine-readable form to STDERR.

Best wishes

Norbert
