I think the Guardian has a better explanation of what's proposed:
www.guardian.co.uk/world/2012/dec/18/ireland-legalise-abortion-life-risk
They say, "The reforms are expected to allow terminations where there is a medical risk to a woman's life or when she is thought to be in danger of killing herself."
So at least they say that doctors can perform an abortion if a woman faces fatal risk, as should have been clear in Savita Halappanavar's case. But mere suffering by the woman, or risk to her health, doesn't get a mention at all.
The health minister makes it pretty clear how enthusiastic the government is about this whole business:
"We must fulfil our duty of care towards [pregnant women]. For that purpose we will clarify in legislation and regulation what is available by way of treatment to a woman when a pregnancy gives rise to a threat to a woman's life. We will also clarify what is legal for the professionals who must provide that care while at all times taking full account of the equal right to life of the unborn child."
