#6 Specify threshholds for each file system individually

[HarryM]

Be able to specify threshhold for each individual file system. I have added these fixes, and provide the updated files, in diff -u format, attached. You may include these if you wish, or rewrite them, or ignore them. I just thought, perhaps, others in the community might enjoy these changes.

Here is a minor update (sorry). This version prints the actual percentage of disk space used, not the threshhold that has been surpassed. I find this is more useful to me.

This time, I am sending the files in tar format.

This is an old request, but I did want to thank you for submitting code. The primary issue with the proposal is that it breaks existing configurations, as it re-defines the format of the diskfull_threshold. I'll also note that there is another option already coded, which is the $diskfull_exclude_dirs, which allows for suppressing of the "disk filling up" message for specific filesystems. Also, the underlying code has substantially changed from the patch.
