Bug 32858, 39372, 70498, 43090, 51758 and 77890 add exceptions to the null check rule of check-webkit-style so that check-webkit-style won't warn about NULL usage in some GTK functions such as g_*() and gst_(). However, the implementation of the null check in check-webkit-style only matches one line at a time so that it fails to match if a function spans multiple lines. For example, check-webkit-style emits a style error if g_object_set spans multiple lines as in https://bugs.webkit.org/show_bug.cgi?id=118657#c20
