Comment (by kcrisman):
This is fine; in the meantime I did get around to implementing this.
However, I also moved the prec evaluation to the _do_sqrt function as
well, since it seemed consonant with your review.
After thinking about it, it also makes more sense do that because if for
some reason something lands in sqrt with prec which isn't RR, Rational,
Integer, etc. then _do_sqrt() should still make the square root be in RR
if x is positive; the previous behavior was to automatically put it in CC.
Does this seem okay?
