Apologies for wrong commit error

While trying to use git,

I made a mistake by changing the merge
field of my branch in my local configuration file.

  On the next
git push
I used, my branch was suddenly pushed to origin/master
instead of my branch on remote server,
despite having a 
push line in my config file...

  I hope that I was able to undo my
wrong commit by this second one:
