wcmd: Fix redirecting a pipe to another pipe

[Reece Dunn]

2009/1/11 Erich Hoover <ehoover at mines.edu>:

+                /* If a redirect is immediately followed by '&' (ie. 2>&1) then
+                    do nor process that ampersand as an AND operator */

Shouldn't that be "do *not* process that ampersand"?
