[NTG-context] Help on tweaking alignment, page numbers and ToC

[Nicola]

Hi,
I still have an issue with blank pages...

Yes, the ToC takes a single page. The makeup seems to insert a blank
page afterwards. MWE:

    \setuppagenumbering[alternative=doublesided]
    \definemakeup[ToC][align=middle,pagestate=start]
    \starttext
    \startfrontmatter
      \startmakeup[ToC]
        \placecontent
      \stopmakeup
      \input{knuth}
    \stopfrontmatter
    \startbodymatter
      \dorecurse{10}{\chapter{Foo}}
    \stopbodymatter
    \stoptext

How do I suppress the blank page after the ToC?
