Nope.  value.h doesn't generally seem to have comments; but since really
it should, I've done this:

/* Release values from the value chain and return them.  Values
   created after MARK are released.  If MARK is nullptr, or if MARK is
   not found on the value chain, then all values are released.  Values
   are returned in reverse order of creation; that is, newest
   first.  */

extern std::vector<value_ref_ptr> value_release_to_mark
    (const struct value *mark);


Then in value.c I added the usual:

/* See value.h.  */

std::vector<value_ref_ptr>
value_release_to_mark (const struct value *mark)
{
...
