Constraining bonds that don't include hydrogens

Hello,

Does changing the line, in Molecule.C (as I have seen in the mailing list):
} else if (atoms[atom_number-1].mass <=3.5) {
to
} else if (atoms[atom_number-1].mass <=3.5 || strcmp(atom_type,"D")==0 ) {
also change anything else but the constraints ?

Does this line mean that, for every atom named "D", the bonds between "D"
and what is bonded to it will be constrained (to the value of the bond
length) ? And is there any other unintended consequences from considering
"D" as a hydrogen ?

Thanks in advance,
