Auto update develop branch

[mrobinson-compass]

When creating new feature it would be great if GitFlow would auto update the master branch if it is out of date.

Thanks for the suggestion. You are mention both auto updating the develop branch and the master branch Which one do you mean? :-)

Develop would be the more useful one as it is used more regularly, but I both would be a good improvement.

@jakobehn I believe he means if finishing a feature, and the (local) develop branch is behind, then have an option to pull the develop branch before merging.

For example, when finishing a feature, we can run into the following error:
`
Error: failed to push some refs to
Error: hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.
