            Bug ID: 21200
           Summary: clang-format single-line enums
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs

Using clang-format 3.6 (svn218873), a single line enum

enum Foo {FooA, FooB, FooC};

is always converted to multiple lines,

enum Foo
{
    FooA,
    FooB,
    FooC
};

if ColumnLimit=0. In order to keep the single line format, ColumnLimit has to
be set to something large (and BreakBeforeBraces needs to be something other
than GNU or Allman).

I would expect the single line to be preserved when ColumnLimit=0 -- perhaps
always, but at least when BreakBeforeBraces is something other than GNU or
Allman.

If the latter, it would be useful to have an option to enable one-line enums
regardless of the value of BreakBeforeBraces (in the same way that
AllowShortXXXOnASingleLine allows for one-line functions etc. even with Allman
and GNU brace placement).
