Weird errors printing strings

[skx]

This is almost certainly going to turn out to be related to expansion.

Consider this program, to print a string five times:

repeat 5 { puts " * " }

Works just fine:

$ ./critical newline.tcl 
 * 
 * 
 * 
 * 
 * 

Result: * 

Now remove the spaces:

repeat 5 { puts "*" }

And suddenly:

frodo ~/critical $ ./critical err.tcl 
*
*
*
*
*
Error running program:function argument mismatch, * takes 2 arguments, 0 supplied

Replacing * with +, or similar, produces the same error message.

Edit - This is caused by the way the return-value is handled from our repeat/for methods and is a simple fix :)
