The documentation for OutputPage::addWikiMsg(...) seems to indicate that the proper form is:
addWikiText( $this->msg(....)->plain() )
but a bunch of places seem to use:
addWikiText( $this->msg(....)->text() )
This double-expansion is probably harmless, but these should probably be changed to use ->plain() or (even better) addWikiMsg(...) instead.
