In some more complicated loops, we do need to use 'goto' to exit from
an inner loop, or to jump to cleanup or an increment of an iterator
immediately before the next loop iteration. However, in these simple
cases, jumping to a label immediately before the 'while' keyword is
unnecessary: we can use an equivalent 'continue' statement for flow
control.
This makes it easier for maintainers to notice the loops where we are
doing something more complicated, which still use 'goto', and know
that they need to pay more attention in those cases.
