In git merge commits (one's which have more than one parent) the parents
are sequential and git uses this ordering.
When you merge some-thing, the first parent is the branch your on
(merging to) and the second (and so on) is the branch your merging from.
Git merge formats commit message so that if you see a message like:
Merge branch 'new-feature'
then the first parent was the branch was master and the second was
Gitk uses the parenting order so that (in most cases) the left hand most
part of the graph is the branch your looking at, all branch to the right
are ones that have been merged to it.

Hope the above helps. :)
