When not all optional arguments are used the space after the last given argument is gobbled. This was normal behavior for a long time until you changed the code in MkIV to keep them.

Hi, What does that mean? Is that going to be changed? How should \date[] be used now in the text? For now, I do it like "bla \date[d=3]\ bla". Is there a nicer way? TIA for any hints, -- Peter
