And I guess my usual redefinition of \dots as
\def\dots{\thinspace.\thinspace.\thinspace.\thinspace}
stems from one of that discussions.

But let me please revive the subject of this thread:
My problem is not with \dots, but with \index within a header command  
like this:

\setuphead[Titel][page=yes, number=no, textcommand=\TitelFrame]
\def\TitelFrame#1{\index{#1}%
	\framed[
		width=\textwidth,
		height=7.5mm,
		frame=off,
		align={right,high}]%
	{\hw\tfa #1}%
}

I can't tell if it's an expansion problem, but that's probable,  
because a single \index{foo} works.

Here's a rather minimal working example that shows the index problem  
(even if not the failure with my actual project):

\starttext

\def\MyTitle#1{{\index{#1}\bfa #1}}
\setuphead[chapter][page=no, number=no, textcommand=\MyTitle]


\chapter{Lalala}
\input tufte

\chapter{Bingo}
\input tufte

\chapter{Abrakadabra}
\input tufte

\completeindex

\stoptext
