Uncrustify space after // in a wrapped command line

I am using uncrustify with the following parameter:

sp_cmt_cpp_start                = force         # Add space after opening '//'
cmt_width                       = 78  

Input:

bi.dwSize = sizeof (bi); //Size of the structure itself, must be initialized with sizeof(CGOSBOARDINFO)

Conclusion:

bi.dwSize = sizeof(bi); // Size of the structure itself, must be
                              //initialized with sizeof(CGOSBOARDINFO)

But after // in the second line "// initialized" it should look like :

bi.dwSize = sizeof(bi); // Size of the structure itself, must be
                              // initialized with sizeof(CGOSBOARDINFO)

Does anyone have an idea how to fix this little problem?
