Boris discovered while investigating bug 89780 that the html serializer never looks at the nsIDocumentEncoder::OutputWrap setting. It should be possible to specify html output wrapped or unwrapped, independant of the other format vs. raw flag settings. Fortunately, the serializer already has wrapping code; it just has no way to disable it (if the passed-in wrap column is zero, then it sets it to 72 and never looks at the flags). That part is easy enough to fix, and it's probably safe to set mMaxColumn to zero in that case, but then in places where it's used, we need to check for zero and call the appropriate method.

My current patch for bug 422403 (not yet landed) fixes this issue. We could close this bug when my patch will be in the trunk.
