These lines are indented as though they were `knr-argdecl-intro' lines.
Return nil when we're not in such a construct.
This function is for historical compatibility with how previous CC Modes (5.28
and earlier) indented such lines.
Here is an example:

doc: /* Move point right N characters (left if N is negative).
On reaching end of buffer, stop and signal error. */)
