Wide descriptions protruding into the margin

Wide descriptions protruding into the margin

[Marco Patzer]

Hi,

with wide description heads I have the problem that the following
description protrudes into the margin.

\definedescription
  [description]
  [alternative=hanging,
   width=broad]

\starttext
\startdescription{conclusion that}
  \input knuth
\stopdescription

\startdescription{conclusion that the designer of a new system must not only be literally}
  \input knuth
\stopdescription
\stoptext

In the second case the “Thus,” should be placed on the line after
the head. How do I achieve that? My current workaround is to append
a \hbox{  } to the problematic entries.


Marco

you can hack the hanging alternative and substitute a glue for
the kern that is used for spacing (strc-con.mkvi):

But maybe this could be made an option?

This works perfectly. Thanks a lot for digging into the sources.
