        <pre>To reproduce, create a .clang-format config file:

    BasedOnStyle: Chromium
    ---
    Language: Java
    BasedOnStyle: Google
    ---

Then the following command wrongly put everything on the same line. 
    % clang-format -i .clang-format

This leads to the following error subsequently (when using clang-format on
other files):

    YAML:1:39: error: Unexpected token. Expected Key or Block End
    BasedOnStyle : Chromium-- - Language : Java BasedOnStyle : Google-- -
                                      ^
    Error reading /dummy/.clang-format: Invalid argument

This is likely to happen (and surprising) when formatting a whole code base:
    % git ls-files | xargs clang-format -i</pre>
        </div>
