[NTG-context] dot and comma in two consecutive cases

24 May 2009

      Hi,

I have this:
\startformula
  z_k = \startcases
    \NC x_k    \MC 1 \leq k \leq N \NR
    \NC y_{k-N} \MC N+1 \leq k < N+M \NR
  \stopcases t_k = \startcases
    \NC r_k    \MC 1 \leq k \leq N \NR
    \NC s_{k-N} \MC N+1 \leq k < N+M \NR
  \stopcases
\stopformula

but I want to punctuate that.

When I do:

\startformula
  z_k = \startcases
    \NC x_k    \MC 1 \leq k \leq N \NR
    \NC y_{k-N} \MC N+1 \leq k < N+M \NR
  \stopcases, t_k = \startcases
    \NC r_k    \MC 1 \leq k \leq N \NR
    \NC s_{k-N} \MC N+1 \leq k < N+M \NR
  \stopcases.
\stopformula

the dot and the comma appear too much separate from cases.

How can I get the "normal behaviour"?

Thanks in advance,
Xan.
