Another example:

<before.cc>

void WebRtcIlbcfix_HpInput(
    int16_t* signal, /* (i/o) signal vector */
    int16_t* ba,     /* (i)   B- and A-coefficients (2:nd order)
                              {b[0] b[1] b[2] -a[1] -a[2]}
                              a[0] is assumed to be 1.0 */
    bool dummy);

Formatting:

% clang-format --style='{ColumnLimit: 80}' before.cc > after.cc

<after.cc>

void WebRtcIlbcfix_HpInput(int16_t *ba, /* (i)   B- and A-coefficients (2:nd
                                           order) {b[0] b[1] b[2] -a[1] -a[2]}
                                                 a[0] is assumed to be 1.0 */
                           bool dummy);

Lines 3 and 4 exceed the column limit.
