Newbie Git question: I have a repo set up on bitbucket. I git fetched someone else's changes and would like to merge them with my own. However, when I try to git merge (or git merge origin/master), I get the message "error: Your local changes to the following files would be overwritten by merge:", and then a list of files I've changed. Having Git merge these changes is exactly what I want to do though.
You can either commit your changes before you do the merge, or you stash them:
git stash
git merge origin/master
git stash pop
