Comment:

 #1314 was another version of this.

 As of r8212 there's some support for specifying a snap-to-vertex tolerance
 in the low-level ptarray_substring function. That tolerance was used in
 turn to solve the problem of using a pre-existent vertex as a location.

 Still, it'd be nice to make the whole set of functions more robust
 numerically
