I have been setting bibliographies using the following instructions:

\definehead[BibTitle][subject]
\setupsectionblock[BibTitle][number=no,page=right]
\setuphead[BibTitle][style={sc},after={\blank}]

\def\hangover{\hangafter=1\hangindent=1.5pc\raggedright}
\definestartstop[bibliography][
  before={
    \page[no]
    \indenting[never]
    \startalignment[left]
    \BibTitle{bibliography}
    \stopalignment
    \bgroup\appendtoks\hangover\to\everypar
    },
  after={
    \egroup
    \indenting[yes]}]

Is there a way to control the degree of the raggedness of the right margin---other than by inserting hyphens manually when feasible? I need lines that are somewhat closer to justified than I am currently getting.
