The delayed progress API is being simplified so I'll probably do a
bit of evil merge while merging this to 'pu'.

I just realized that this patch got lost :-(

Really?  Isn't it 52f1d62e ("convert: display progress for filtered
objects that have been delayed", 2017-08-20)?  It already is in
'master' since about 3 weeks ago.

As this is merely a new "feature", I do not think it is reasonable
to expect it to be merged down to 'maint'.  In fact, I think your
original patch [ref]
declared that its Base Ref was "master", and I queued the topic on
top of the then-current 'master', so it is not mergeable to 'maint'.

It may be cherry-pickable, but I do not think it deserves to be.  It
is not a fix for a grave bug or anything like that, right?
