#3 C/C++ bit fields get a line feed

[Thomas Dorner]

C/C++ bit fields are (incorrectly) treated like labels:

struct A {
int a:1;
};

will become something like

struct A {
int a:
1;
};

instead of keeping the "1;" in the same row. This is
identical behavior to the original AStyle, see their
bug report 1238641 as reference (including a hacked
solution proposal by me).
