[NTG-context] cropmarks

[wwl at musensturm.de]

Hallo!

The following:
-------
\definepapersize	[RM]	[width=170mm,height=240mm]
\setuppapersize	[RM]	[A4]
\setuplayout	[marking=on, location=middle]
\starttext
Bla
\stoptext
-------
results in 163mm width and 230mm height.
What is wrong here?


A second observation: file 'rm.tex' with

\startenvironment rm
...
\stopenvironment

is not found
in 'test.tex' with

\environment rm
...

renaming to 'whatever' helps
