As Uli Kohler said, statsmat.hlp was messed up at the end (and it
showed up that way on my OS X system as well). I tweaked it by making
two changes that should not matter:
The first change was to alter (space)\n to \n: that is, remove a blank
space. The second change, as you can see, is to remove a space before
the }. With those changes, it now SMCLs properly in the Viewer with
rnethelp (for me, anyway). I'd be interested in knowing whether it
works for Uli now.
