Re: [NTG-context] Probelm with \defineenumeration

I have defined an enumeration. After typesetting the enumerated list I get
on the first line the enumeration text and lost and alone in front of the
second line the enumeration number.
Is this something I do in a wrong way or is there a bug?
hm, this is due to the fact that the [ ] are not taken into the width 
calculations. This problem was introduced some time ago when i made a 
slightly more advanced width multiline calculator. In your case it's also 
triggered by text=\em which should be textstyle=\em  (now an extra space is 
added between the text and number)

The next alternative fixes the width calculation.
