(A)
I've found a promising option compress=no|yes|all in an experimental test
case located in the strc-reg.mkiv file. The corresponding lua code seems to
be performing some cleanup of page ranges, but when I define it same way,
there is no difference in my output (still 1-1):

\startregister[index][range_01]{primary}
Dummy text.
\stopregister[index][range_01]
\placeregister[index][compress=yes]

Is it necessary to switch it on somehow? 

(B)
I've also found a special syntax for collapsing pages in
http://wiki.contextgarden.net/Registers
[[Command/{{{1}}}|\{{{1}}}]] - but I have no idea how to appply it. 

I already use the 'command' parameter to switch the index group letter to
upper case: \setupregister[index][n=2,command=\Word,style=normal]

Can these commands be combined together somehow? Or is it obsolete in favor
of (A)?

Thanks, Jan
