Jean-Michel pointed out to me the following curiosity:
\starttext \input tufte \startalignment[middle] \input ward \stopalignment \input tufte \stoptext
The startalignment applies to the preceding text, too. Strange... It’s a normal behaviour for TeX, the question is should \startalignment end the previous paragraph or not.
when tex breaks a paragraph into lines the current values of relevant parameters is used (left and right skips, spacing, etc) \bgroup \raggedright \inptu tufte \par \egroup \bgroup \raggedright \inptu tufte \egroup \par
I never noticed this before as I have the habit of coding \startalignment\stopalignment blocks set-off with leading and trailing blank lines for better readability. But such practice could lead to undesired results. Consider the following example:
\setupwhitespace [big]
\starttext \input tufte
\startalignment[middle] \input ward \stopalignment \input dawkins \stoptext
So \stopalignment implicitly imposes a \par. If I were to omit the blank line before \startalignment so that no big whitespace be included before the centered block, the tufte text will get middle aligned. Also, perhaps I might not wish for the dawkins text to be separated by a big whitespace, logically as in: You can use \startpacked … \stoppacked to suppress blank lines inserted by \setupwhitespace.
