Thanks for the patch. But in fact, I think URLs should not be broken into
lines, because in the browser's text field they should not be entered
with a newline either.

I therefore chose to avoid the ugliness by inserting a line break before
or after the URL.

        Avoid "overfull hboxes" in the TeXed documentation.
        * doc/libunistring.texi (texnl): New macro.
        (Unicode, Autoconf macro): Use it.

        Bidirectional category): Likewise.
        * doc/uniwbrk.texi (Word break property): Likewise.

address@hidden Macro for forcing a line break in TeX mode.
address@hidden Needed because there are long unbreakable pieces of text (such

considers only
