Description:
        [Detailed description of the problem, suggestion, or complaint.] 
An input redirection placed before the loop construct fails, while the same 
redirection placed behind succeeds. Same happens on Sun Solaris 8 (sun4u) with 
bash 2.03.0(1)-release (sparc-sun-solaris) and even with the original bourne 
shell.
