inheritting from the latter) . bodypartformatter.h forward declares
only KMail::HtmlWriter and in the KMail::Interface::BodyPartFormatter
interface it defines it specifies 'HtmlWriter' as argument to the format
method. If bodyformatter.h is included in some file that already
included htmlwriter.h, so that KMail::Interface::HtmlWriter is known as
well, then the HtmlWriter for format is picked up as
KMail::Interface::HtmlWriter, as BodyPartFormatter is in Interface.
Without such an inclusion KMail::HtmlWriter is picked up. This sometimes
confuses gcc. Till said he assumes the richer KMail::HtmlWriter is
actually meant here, so I'm making that explicit here.
