I've never heard of a buck, boost, or buck/boost regulator.

Now you have:

http://www.national.com/pf/LM/LM2698.html




There are
bucking, boosting and buck/boost transformers,

No transformer in the above link.

but if the voltage is
boosted, it is at the expense of a corresponding same percentage loss of
available current, plus transformer loss.

Only applies to transformers. Power (voltage and current over a given time
period) is conserved.

Interesting. If the power source is a 12 volt DC battery, what does this
regulator boost and how does it do it?

My apologies. I didn't notice the link you provided.
It appears to be an inverter circuit and indeed can provide a DC boost.
However, it's not a perpetual power system and will still use more power
from a battery that it is trying to charge.

DC-DC converter. I see there are references to Buck Regulators on the
I-net. But Buck just means reducing voltage.
