I've realized that empty line is placed before every Index section where
\testcolumn command is placed (by my patch).
Is there any way to use \testcolumn and avoid producing that empty line?

I've found the corresponding code in strc-reg.mkiv:
\setvalue{\??registerindicator a}#1%
{\registerparameter\c!before
% bugged, why does leftskip gets set:
\vskip\lineheight\goodbreak\vskip-\lineheight
\begingroup
\useregisterstyleandcolor\c!style\c!color
\dontleavehmode
\strut
\iflocation
\dosetdirectpagereference{\currentregister:\v!section:#1}%
\fi
\registerparameter\c!command{#1}%
\endgroup
\blank[\v!samepage]%
\registerparameter\c!after
\par
\nobreak}
That (2) case can be fixed by a small change:
\testcolumn[3]\registerparameter\c!command{#1}%
But when tested on this MWE, you can see a drawback - the first letter (p)
starts always on the second line (not on the first one):
\setupregister[balance=yes]
\starttext
\index{primary+secondary+tertiary}
\index[primary long]{\dorecurse{5}{primary long }}
\index[primary longer]{\dorecurse{5}{primary longer }}
\input{tufte}
\completeindex
\stoptext
Can this issue somehow be eliminated? Tested on the last beta (with my
patch).
That (1) case is still open. I have no idea how to accomplish something like
this using (Con)TeX(t) syntax :-(
Thanks, Jan

After finishing another duties I am back ... and still facing these issues.
I think both cases could be eliminated by establishing a new constraint to
the 'key letter':
(1) There must be 0 or at least 3 lines at the beginning of the
page/column before the Key letter.
(2) There must be at least 2 lines after the Key letter.
Can this be somehow set in my source file?
Thanks, Jan

[NTG-context] Orphans/Widows in the Index
Dear All,
in my auto-generated two column index (registry) there are several cases of
widows - it is the last item of the given letter which overflows to next
column/page:
--- (start page) ---
Usti 29 (!!! - I would expect to place here also one or better two
previous entries)
V
Vamberk 18
...
...
There are also few cases of orphans, but this is not so strange:
...
...
Josef 29
K (!!! - both these lines could be moved to the next
column/page)
Karel 69
(end page) -
In my setup I have defined:
\startsetups[grid][mypenalties]
\setdefaultpenalties
\setpenalties\widowpenalties{2}{1} % change to {3}{1} doesn't
help
\setpenalties\clubpenalties {2}{1}
\stopsetups
\setuplayout[grid=yes, setups=mypenalties]
It is hard to provide MWE. Moreover, the content is for private use only.
Is there any remedy for this?
Thanks, Jan
