The merge of the latest features from Liam into the Experimental branch
raises the question of best practices for merging. In particular, I am
not sure that merging multiple features at one time is a good idea.
Other projects seem to divide commits into the smallest possible pieces.
I think that this is good practice as it better documents what is being
committed, allows for better reviews, and makes it easier to cherry-pick
from one branch to another.

In particular, the commit message:

"Merge in ponyscape features by Theo and worked on my LiamW"

doesn't give any information about what are the purpose of the changes.
It takes reading the code and/or searching the web to find this
information.
