  We here show that, even in the absence of "regularizing" microscopic effects
(viz. slip at the wall or the disjoining pressure/precursor films), no
singularities in fact arise for a moving contact line surrounded by the pure
vapor of the liquid considered. There are no evaporation-related singularities
either even should the substrate be superheated. We consider, within the
lubrication approximation and a classical one-sided model, a contact line
advancing/receding at a constant velocity, or immobile, and starting abruptly
at a (formally) bare solid surface with a zero or finite contact angle.
