Subject: [PATCH v2 1/2] clang-format: do not allow short enums on a single
 line

From: Michael Riesch <michael.riesch@...fvision.net>

clang-format 11 introduced the option "AllowShortEnumsOnASingleLine".
Set it to "false" in order to avoid short enums of the form:

    enum my_short_num { green, red };

With the option set to "false", they will be converted to

    enum my_short_num {
            green,
            red
    };

which is consistent with the definition of enums with more items.
