Other options use quotes as well in their description in this area.

Both sound pretty much the same to me.

"Prepare for two-phase commit" may be clearer?

Hmm. The internals of 63cf61c refer to a "STREAM PREPARE", still the
protocol docs are quite messy ("prepare", "prepare timestamp", etc.)
so more consistency would be appropriate, it seems. Amit?

The part for the protocol messages with 2PC and logical replication
could use a larger rework. I have left these for now, and fixed the
rest of the typos you have found.
