Summary

clang-format-7 -style="{BreakBeforeBraces: Stroustrup}" wasn't doing
the same as the doc

Looking into this, I think your update of the example below is correct, but the description should stay as-is:

Like ``Attach``, but break before function definitions,...

The Always break before braces should still apply to the BS_Allman option below.
Am I missing something here?

Remove the desc update

Thank you!
