    @massimo: pretty please use git :)
    
    It would be really nice if others, and prolifix people like
    you, prepared git formatted patches, so that it is much saner
    and easier to push and work with contributions as a maintainer
    with a dirty tree, and in even more valuable bugs than this
    one.. without needing to re-read and re-understand the entire
    context of the fix, before fully reimplementing it.
    
    This commit fixes bug #787441, where NaN is polluting the
    computer error/tolerance.
