[NTG-context] setupitemize reverse not working with start value

[NTG-context] setupitemize reverse not working with start value

[Aditya Mahajan]

Hi,

When reverse option is set in \startitemize, the value of the start key is ignored. MWE:

\starttext
\subject{Without reverse}
\startitemize[n][start=3]
  \item Four 
  \item Three
\stopitemize

\subject{With reverse}
\startitemize[reverse,n][start=3]
  \item Four 
  \item Three
\stopitemize
\stoptext

What can I go if I want reverse numbering starting from a particular value.

Aditya

Changing this in strc-itm fixes the behavior, but I am not sure if this is the right place.

Should be fine, the few things I tested produced correct results.
