Commited to wrong branch

[Howard Miller <howard@e-learndesign.co.uk>]

Hi,

I am resurrecting a discussion from a week or two back (been on
holiday).  As follows...

I had made some changes to some files and then done a commit. Only
then did I realise that I had the wrong branch checked out. To make
matters worse I then did a 'git reset HEAD^' which means that I can
now no longer switch branches. I am stuck. I had some advice (thanks!)
but it was not complete. I'd appreciate some more help.

I was advised to do a 'git reflog --branchname--' (I don't
know/understand what this command does) but it doesn't work. I just
get 'usage: git reflog (expire | ...)'

So basically I am no further forward. Just to reiterate I need to...

* remove the commit from my current branch (it tracks a remote so I
would prefer there to be no evidence to confuse other people after I
push)
* add the changes to the (other) branch they should have been added to.
* not loose or break anything.

Any (more) help appreciated.
