Pushed this. I noticed that the paragraph that described MERGE in the
read-committed subsection had been put in the middle of some other paras
that describe interactions with other transactions, so I moved it up so
that it appears together with all the other paras that describe the
behavior of specific commands, which is where I believe it belongs.
Thanks!
