Summary: string equal example wrong in doc

Initial Comment:
The following code appears in the documentation for string, as an example of using string equal:

Test if the string in the variable string is a proper non-empty prefix of the string foobar. 
set length [string length $string]
if {$length == 0} {
   set isPrefix 0
} else {
   set isPrefix [string equal -length $string $string "foobar"]
}

It has an unnoticed bug: the variable after the -length should be $length, not $string.
