Mass Heal not hurting undead when used offensively

[Gwain]

This is a bug I've noticed before but I always forget to report. Apparently Mass Heal heals undead instead of harming them. I've tested it twice and found it restores them to health and did not harm them.

Its very hard to test this in the game because mass healing usually heals them to well, so I can't confirm if this is for all dead. I will say that I saw it significantly heal the vampire in Thesk.

Confirmed.

d20 would have it work; however, I think hard code needs to be added to make that the case. Currently the cure spells use the flags
GENERIC_SPELL_FLAG_NORMAL 1
and
GENERIC_SPELL_FLAG_UNDEAD 3
to provide the different behaviour on the two groups.

The mass spells use the flag
GENERIC_SPELL_FLAG_MASS
and there is no
GENERIC_SPELL_FLAG_MASS_UNDEAD or the like that would allow for mass and undead differentiation at once.

This is pushing my knowledge of spell code, but I think that's the deal. Short of hard code, should the spell do all its damage on one undead, or the helpfiles be amended to specify that the mass spells do not harm undead?
