-Subject: Fix sign of input to bsloww1 (BZ #16623)

-
-Fix sign of input to bsloww1 (BZ #16623)
-
-In 84ba214c, I removed some redundant sign computations and in the
-process, I incorrectly got rid of a temporary variable, thus passing
-the absolute value of the input to bsloww1.  This caused #16623.
-
-This fix undoes the incorrect change.
-
-[nix]: drop docs update (wouldn't apply)
