bug#20208: 25.0.50; c-mode: incorrect fontification of simple enums (again)

[Dima Kogan]

Hi. This is very similar to bug 19669. I'm running emacs from revision
6e1fac9, which has the fix to bug 19969: revision d69e9f1c.

I'm opening a file tst.hh (attached). Then "emacs -Q -nw tst.hh". Then
any interactive command (M-x, for instance). The result has
fontification issues, as shown by the attached image.


enum class error_t
{
        xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx                                     
  = -1,
        xxxxxxxxxxxxxxxxxxxxxxxxx                                               
          = -3,
        xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx             = -4,
        xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx                       = -5,
        xxxxxxxxxxxxxxxxxxxxxxxxx

        xxxxxxxxxxxxxxxxxxxxxxxxxx
