svn commit: r43630 - head/share/xml

[Gabor Kovesdan]

Author: gabor
Date: Wed Jan 22 14:34:08 2014
New Revision: 43630
URL: http://svnweb.freebsd.org/changeset/doc/43630

Log:
  - Line wrap indicators are rendered in the verbatim texts with the help
    of soft hyphens. However, FOP does not handle well soft hyphens when placed
    after certain characters. Apply a workaround for this.
