[bug-gawk] Gawk manual: local variables are initialized to the empty string

[Hermann Peifer]

Hi,

I see that there is quite some update work done around the manual. One 
thing that confused me (and maybe only me) is the above statement 
mentioned in the context of user-defined Functions, in sections 6.4 and 
9.2.1

"initialized to the empty string" made me believe that something like 
this happens in the background, which would make localvar a scalar 
inside the function:

localvar = ""

This is obviously (luckily) not the case und local variables are 
"untyped variables", as the debugger tells me.
