well if we *really* want to be flexible, how about this:

## fetch a particular option from mysql's invocation
#
# usage: void mysqld_get_param option
mysqld_get_param() {
        /usr/sbin/mysqld --print-defaults \
                | tr " " "\n" \
                | grep -- "--$1" \
                | tail -1 \
                | cut -d= -f2
}

# ...

pidfile=`mysqld_get_param pid-file`

so, in the future, if we want to grab something else, it should be
pretty easy to do.

since it's a fairly small change, so i'll go ahead and commit it directly
to both trees.
