Looks good from here (autoconf 2.13) with one minor complaint: I'm seeing
things like this from --help for long parameters:

  --enable-optional-hook-export example optional hook exporter
                              ^^^

Any way we can make it put an extra space in there like we used to have,
just to make it more readable? Just count how long the parameter string
length is and add an extra space to the help string if over some constant.
I'd do it but I'm no m4 guru. :)

Yeah, what I'd really like to see happen is that we do a line break 
like what autoconf-2.5+ does when we exceeed the 26th column.

Trust me, I spent over an hour trying to do it and I gave up.  The
easy way to make it look nice is to upgrade your version of autoconf
or find a m4 guru.  Because I'm sure not one.  =)   -- justin
