+Ah, it looks like a recent version changed the default behavior to do the
+right thing, and inverted the sense of the configuration option. (Either
+that or Gentoo did it.) So you need to set the
+"no-strip-whitespace-before-send" option, unless the option you have is
+"strip-whitespace-before-send", in which case you should avoid checking
+it.
