The first cut line described in Trig.Rd for asin() is incorrect in the ascii
version of the manpage.

The Rd file reads:

 For \code{asin()} and \code{acos()}, there are two cuts, both along
   the real axis: \eqn{\left(-\infty, -1\right]}{\(-Inf, 1\]} and
 
Note the inconsistency between the ascii and latex equations.
It should read:

 For \code{asin()} and \code{acos()}, there are two cuts, both along
   the real axis: \eqn{\left(-\infty, -1\right]}{\(-Inf, -1\]} and


where the final "1" has been changed to a "-1".  Ref:  AMS-55, page 79,
figure 4.4.


It's very difficult to catch this kind of error: thanks to Kjetil Halvorson for
his sharp-eyed comment.
