#! probably incorrect historicism in manual

[Reuben Thomas]

The manual says:

"A few ancient 4.2BSD based systems (such as Dynix circa 1984) required a 
single space between the `#!' and the `/'.  However, these ancient systems 
are no longer of practical concern."

This is probably not actually correct. See detailed debunking of this 
apparent myth at:

Since it's definitely irrelevant for users of autoconf (it seems pretty 
clear that autoconf won't work on any such system even if it does exist) I 
suggest you remove this paragraph from the documentation and leave the 
matter for historians to argue.
