Squash commits

# Get the base commit for your branch
$ git merge-base your-branch master

# Use the hash returned by the previous command to rebase
$ git rebase -i <HASH>

# Previous command will open up your text editor with something like this:
#   pick 1fc6c95 do something
#   pick 6b2481b do something else
#   pick dd1475d changed some things
#   pick c619268 fixing typos
#
# Replace `pick` for `squash` in all lines but first, like this:
#   pick 1fc6c95 do something
#   squash 6b2481b do something else
#   squash dd1475d changed some things
#   squash c619268 fixing typos
# Save and close the file, wait for a new instance of your text editor,
# edit your commit message and enjoy your brand new commit!
