Use a project's .clang-format file?

It looks like, from the preferences, that there is an enforced clang-format style. Because of the existing, already-filed issues about in-tree builds, I haven't tried this against any of my own big projects, I don't know for sure, but it would be preferable if the app defaulted to using a project's .clang-format file (as the --style=file command line flag semantics work) before falling back to a system-wide preference.
