Re: @url doesn't work correctly within @raggedright environment

[Karl Berry]

Hi Werner,

    address@hidden
    POSIX specification:@* 
@url{http://www.opengroup.org/onlinepubs/9699919799/functions/posix_spawn_file_actions_addclose.html}
    ...
    and `make gnulib.pdf' produced a result as shown in the attached
    image...

Namely (for the record), the potential stretchiness around the special
characters in the url still had effect.

I made the diff below, which seemed to fix this case.

Thanks,
karl
