gnulib.pdf formatting issues

[Werner LEMBERG]

Two suggestions to improve formatting of gnulib.pdf:

. To avoid thousands of overlong lines, replace

    POSIX specification: @url{...}

  with

    POSIX specification:@*
    @url{...}

  I think this is beneficial even for the HTML version of the gnulib
  documentation.

. The patch below (again useful for the HTML version too IMHO) also
  fixes some overlong lines.

There are certainly more issues, but I've just checked the regex
chapter.
