Would it be better to use val_to_str() or val_to_str_const() in cases such as this?

What about changing match_strval() to behave like val_to_str() does (i.e., make IT handle the NULL case), and then just have val_to_str() return match_strval()'s guaranteed non-NULL return value unconditionally?  And also introduce a match_strval_const() counterpart for val_to_str_const().
