Hagen - Pragma ADE

Where additional kerning can make sense, is in titles. The previous command can do
that job. In addition we have a mechanism that fills a given space. This mechanism uses
the following definition:
\setupcharacterkerning
[stretched]
[factor=max,
width=\availablehsize]
\stretched{\bfd to the limit}
t o t h e l i m i t
The following does not work:
\ruledhbox to 5cm{\stretched{\bfd to the limit}}
t o t h e l i m i t
But this works ok:
\setupcharacterkerning
[stretched]
[width=]
\stretched{\bfd to the limit}
t o t h e l i m i t
You can also say this:
\stretched[width=]{\bfd to the limit}
t o t h e l i m i t
or:
\ruledhbox{\stretched[width=10cm]{\bfd to the limit}}
t o t h e l i m i t
