querry related to structure padding

[Chloe Johnson]

The only reason for this reply is that the misspelling in the
subject has been driving me mad. Mad, as in insane, or totally
discombobulated, I tell you.

I rejected quarry and quail as possible corrections.

It is possible that a "querry" is a pre-electronic version of an
equerry. That would be someone who cares for the horses of royalty but
who cannot do so at a distance.
