Thanks.  I've edited a few more places while scanning the whole.

And I'm behind the commit that introduced it (392ea0c78fdb).  It is
possible to remove the dependency to slurp_file() entirely by
switching the second location checking the logs for the checkpoint
completion.

Thanks.  I'm looking at applying that at the beginning of next week if
there are no more comments, to get something by the feature freeze.
We could be more flexible for all that as that's related to testing,
but let's be in the clear.

I've also renamed the test to 041_checkpoint_at_promote.pl, as now
that the original is fixed, the checkpoint is not invalid.  That's
cleaner this way.
