Well, I'm not Dave, but maybe I can answer your question.  I've dealt with
it myself.

Whitespace is allowed on both sides of the equals sign in the
attribute=value pair, including newlines.  The specification allows this
and the browsers I've used have had no problems with it.

However, personally, I use a patched version of HTML Tidy that does not
wrap after the equals sign, just because I don't like it.  In pprint.c,
PPrintAttrValue(), I commented out the three ifs after the first "AddC('=',
linelen++);", including the third if's else (the "if (indent + linelen ..."
ifs, the entire block).  If you want to put a switch on the wrapping after
equals, that's where you'd put it:  around those ifs.

I have an additional patch that only quotes attributes when necessary (yes,
I know X*ML requires they all be quoted, which is why I programmed in an
exception for that case), but it isn't tuned the way I want it.  I prefer
free-form CDATA attributes to always be quoted (such as SRC and HREF) and
only leave unquoted those attributes that take key word values.  HTML Tidy
doesn't know the difference (generally doesn't care about attribute values)
so that step is stalled until I motivate myself to teach Tidy these things
(probably an expansion of the global list of attributes).
