OK for 4.5.

For 4.6 I think one should really consider changing the 700-odd 
fold_build* to fold_build*_loc; for the build* (and build*_v) calls, I 
have to figure out (a) whether is is needed to add the locus and (b) if 
so, how to do this - there are no build*_loc functions. I fear we won't 
do the _loc fix if one commits your patch to the 4.6 trunk.

Thanks for the patch!
