Hi Martin,
I'm pretty shocked how difficult this is... still...
I'm finding git logs and reflogs pretty difficult to read and interpret (head melting) - in particular telling what happened on what branch - but looking at the reflog (which I assume is showing me the actions on the current branch, but I'm not sure) I think I must have made two commits on the wrong branch so the reset has only 'popped' the top one. Other than that your interpretation is correct.
I cannot currently change branches - it only complains about one file. I'm a bit worried about that - I would like to understand why this is a problem but I don't.
So I am now a little hazy on how to deal with previous TWO commits.
Sorry for misery.... I've lost the plot a bit here :-)
Howard
