OK.

More explanation or cross-reference is needed for what "filter value" 
means.

Should state what the default uses.

This says what happens if args is NULL, but says nothing about the meaning 
of a non-NULL value (presumably it's not simply a boolean, or it would be 
bool rather than tree).  Nor is anything said about *how* pop_target 
"specifies the default options to use" (even a reference to code that 
defines how options correspond to trees, for example).

OK if you change "really has type VEC(tree,gc)* ." to "really has type 
@samp{VEC(tree,gc)*}.".
