Details:

Today, I needed to find the subdirs in a large-ish tree where the application
had recently created/updated certain files. So, upon finding such a file, I
would have liked to -prune the directory (and its subdirectories) its entry is
in.

Unfortunately, -prune works only if find is actually looking at the directory
itself; it does not have any defined effect if the "file currently examinated"
is in fact a file.

Would it be possible to implement "-prune $THIS" to, in pseudocode, have the
effect of "-type d -prune $THIS -o -prune `dirname $THIS`"?
