@ -3707,11 +3707,11 @@ Local labels are different from local symbols. Local labels help compilers and
programmers use names temporarily. They create symbols which are guaranteed to
be unique over the entire scope of the input source code and which can be
referred to by a simple notation. To define a local label, write a label of
the form @samp{@b{N}:} (where @b{N} represents any positive integer). To refer
to the most recent previous definition of that label write @samp{@b{N}b}, using
the same number as when you defined the label. To refer to the next definition
of a local label, write @samp{@b{N}f}---the @samp{b} stands for ``backwards''
and the @samp{f} stands for ``forwards''.

There is no restriction on how you can use these labels, and you can reuse them
too. So that it is possible to repeatedly define the same local label (using
