Hans, Wolfgang,
thank you for your speedy reply. However, I still do not know the difference between \leavevmode and \quitvmode. Could you please elaborate?
simple explanation: \quitvmode checks if it's in h mode already and doesn't do redundant mode switching (which involves injecting indentation boxes)
Cheers, Henri

Dear list,
could someone please explain what is the difference between \dontleavehmode and \leavevmode?
Internally, I also stumbled upon \quitvmode. Is this a synonym for \leavevmode? It seems to be primitive.
\leavevmode is kind of useless as it can interfere in spacing so we always used \dontleavehmode in context (a macro) that later was added as primitive \quitvmode to luatex
You sometimes need \dontleavehmode to make sure you enter hmode (esp when you start a paragraph with a group or boxed stuff)
(the only two places in context where \leavevmode is used is in rather plain macros that get overloaded later)
