Commit timestamp abbreviations

I noticed this when looking at the allocated shared memory structures in
head:
shared memory alignment 64-byte of CommitTs Ctl:  0shared memory alignment 64-byte of CommitTs shared:  0

I thought we got rid of the idea that 'Ts' means timestamp.  Was this
part forgotten?
