@vangheem This merges the hotfix into 5.0.

Note that this adds the formatting function and classes from the hotfix into utils.py. So third party code might start relying on this. If we do not want this, then we had better change that now, before merging.

Well, utils.py is probably the right location. if we want to indicate this a thing not to use outside we could prefix all with _ - but I am not sure if this is needed/ what we want.

Since nobody has an opposite opinion on this I will merge it.

@mauritsvanrees - since I'm not totally sure about the intentions of your PR I ask you to correct the wrong import in mixins.py.

@mauritsvanrees you have imported safe_format but using SafeFormatter. This leads to an error mentioned here: #1938 (comment)

Same here.

Huh, strange that this is not caught by the tests.
I have added pull request #1944 which fixes the import and hopefully makes things a bit clearer.
