Re: having problems with gendocs.sh

[Karl Berry]

    gendocs.sh: gawk.html: cannot find image general-program.png
    END failed--call queue aborted, <> line 42670.

    The general-program.png file is present.

The problem was in gendocs.sh itself -- it is what copies the images
into the output directory.  It was only looking in the directories
specified with -I, and not cwd.  I added . to the list and that seemed
to be enough.  I prepended it since makeinfo ordinarily looks in . first.

makeinfo can do more things with -I than gendocs.sh, but hopefully this
will suffice.

Updated texinfo and gnulib.

Thanks,
Karl
