         Remove inappropriate discretionary hyphenation points.
 
         * man/pdfroff.1.man man/pdfroff.7.man man/groff_toc.man (.UR):
         Delete '\%' prefix from URI argument; it was intended to prevent
         hyphenation, but it actually allows insertion of a discretionary
         hyphen, and line break, within the bracketted URI output string,
         between the opening angle bracket and the URI itself.

         (MR_HOST_3_URI_ROOT, MR_HOST_3_URI_PATH): ...define these new macros,
