--css-prefix option no longer adds a hyphen to its built classes #777

Given this file:
<h1>example</h1>
Here's some <font color="#0000FF">blue</font>
And here's some <font color="RED">red<font>
<p></P>
The behavior of assigning classes in 5.7.17 is not the same as in 5.6.0. I don't know if this is a bug or intentional.
Under 5.6.0:
$ tidy --version
HTML Tidy for Linux version 5.6.0
$ tidy -q --css-prefix foo --clean 1 foo.html 2>&1 | grep span
span.foo-2 {color: red}
span.foo-1 {color: #0000FF}
Here's some <span class="foo-1">blue</span> And here's some
<span class="foo-2">red </span>
Under 5.7.17:
$ tidy --version
HTML Tidy for Linux version 5.7.17
$ tidy -q --css-prefix foo --clean 1 foo.html 2>&1 | grep span
span.foo2 {color: red}
span.foo1 {color: #0000FF}
Here's some <span class="foo1">blue</span> And here's some
<span class="foo2">red </span>
So now it makes "foo1" instead of "foo-1" as a class name. Is that intentional? When did it get changed? This affects one of my tests in HTML::Tidy5, which pass under 5.6.0 and no longer pass under 5.7.17.
