[AD] Documentation is wrong about ulimit parameter

[Grzegorz Adam Hankiewicz <gradha@xxxxxxxxxx>]

Hi.

The help documentation says incorrectly that ulimit -c 0 will allow
cores to be dumped.  -c 0 makes cores not dump under my system, hence the
proposed fix. I'm not commiting this because maybe ulimit has different
behaviours under different unices, more precisely, I remember Eric saying
that ulimit -c 0 worked for Suse. Could you please verify which setting
are you using with ulimit?

    Just like with djgpp, to make sense of the core, you should compile your
    program with debugging information (using the -g switch), and then run
