How to make startalignment middle not change the linewidth

How to make startalignment middle not change the linewidth

[Aditya Mahajan]

Hi,
  It seems that startalignment[middle] does not like long lines. 
Consider the following example (not strictly minimal, but I can not 
get such a marginal case with default setup).

\setuppapersize[letter][letter]

\setuplayout[
                  width=middle,
                 height=middle,
               location=middle,
               topspace=.75in,
            bottomspace=0.75in,
              backspace=0.75in,
               cutspace=0.75in,
             leftmargin=0in,
            rightmargin=0in,
     leftmargindistance=0in,
    rightmargindistance=0in,
                 header=0in,
                 footer=0in,
          headerdistace=0in,
         footerdistance=0in,
       ]

\definetypeface[ieee] [rm]  [serif] [times]     [texansi]
\definetypeface[ieee] [mm]  [maths] [modern]    [texansi]

\setupbodyfont[ieee,10pt]

\definefont[TitleFont]   [Regular at 24pt]

\setvariables[paper]
   [ title={Optimal Performance of Feedback Control Systems with
            Limited Communication over Noisy Channels}]

\starttext
{\TitleFont\setupinterlinespace
\getvariable{paper}{title}
\blank[1.0em]\endgraf}

\startalignment[middle]
     {\TitleFont\setupinterlinespace
     \getvariable{paper}{title}
     \blank[1.0em]\endgraf}
\stopalignment
\stoptext

How can I get the same linebreaking as the first case, but with each 
line middle aligned?

Duh, I need to learn how to do font setup correctly and without typos. 
Even with the correction,

\definetypeface[ieee] [rm]  [serif] [times]     [default] [texnansi]
\definetypeface[ieee] [mm]  [maths] [modern]    [default] [texnansi]

the linebreaking is the same as before.

I get the same actual line breaks in both cases, but I wager the
problem is that the 'normal space width' is not equal to the
\spaceskip value that is used inside the alignment.

This in turn is caused by the 'natural' space of the times font
is 1/4 of an em, not 1/3. Try adding

   \def\raggedspaceamount{0.25em}

to your setup and see if that is more to your liking.

Cheers, taco

Thanks. With this definition, I get the same line breaks.
