+Subject: [PATCH] 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.
