"right half" is a mysterious choice #71

Directly before Table 2.20, we have:

"For the purpose of function calls, the right half of VSX registers, corresponding to the classic floating-point registers (that is, vsr0-vsr31), is volatile."

"Right half" is a poor choice of language, particularly with Figure 2.16 across the page showing the FPRs on the left side. We should avoid "left" and "right" descriptions if possible. Also, this is a bit of a grammatical mess. Possible rewrite:

"For the purpose of fucntion calls, the most-significant halves of the VSX registers that correspond to the class floating-point registers (that is, vsr0-vsr31) are volatile."

Well, you know, without spelling it "fucntion."

Should be least-significant halves, also. Confirmed for 1.5.
