Hi,
I'd like to have my \startlines ... \stoplines indented in the
following way: the first two lines unindented, the next two
indented, and so on.  Basically, this means that I'd like the
pattern to be based on (mod 4) arithmetic and not (mod 2).  Is it
possible?  If yes, how?
OK, so I thought I can handle this... but not:(.
I found the relevant definitions in spac-hor.mkiv and tried to add a
line saying
\installindentingmethod
\v!evenpairs{\c_spac_indentation_toggle_state\plusfour}
% there is no \v!evenpairs
\unprotect
% english interface only:
\installindentingmethod
   {evenpairs}
   {\c_spac_indentation_toggle_state\plusfour}
% or maybe:
\installindentingmethod
   \v!quadruple
   {\c_spac_indentation_toggle_state\plusfour}
% as \v!quadruple is a known keyword
\protect
Sorry to say that, but neither seems to work...

? 

What do I do?  (And what do I do if I really want "evenpairs",
especially that I'd like to have "oddpairs", too, so "quadruple" is not
really a good keyword for me?)

TIA,
