View previously merged branches

First, run this:

• git log --oneline --first-parent

Locate the identifier of the desired branch, and the previous one, for example:

961e4f9 Merge remote-tracking branch 'tol/mysql'                                                                                                                                                 
3cb72fb Merge remote-tracking branch 'tol/nfs-requires-rstatd'

So for the mysql branch, run this:

• git log --patch --reverse 3cb72fb..961e4f9
