The leafnames of disk paths are matched against the patterns in the -not_leaf

Pattern matching, if enabled, happens at definition time and not when exclusion
checks are made.
@*
Keep in mind that there may be alternative paths to the same disk file. The
exclusion tests are done literally, so that they do not keep files from getting
into the ISO filesystem by other paths. Accordingly an exclusion does not
prevent a disk file from being overwritten by file extraction via an
alternative not excluded path. So the exlusions need to be coordinated with
the actual disk_path parameters given with commands.

from ISO images and to create, overwrite, or delete file objects on disk.
@*
Disk file exclusions by -not_mgt, -not_leaf, -not_paths apply.
The exclusion tests are made with the paths and names for the disk files.
If exclusion of paths or names in the ISO image is desired, then use image
manipulation commands like -rm or -find ... -exec rm before extraction,
and end the program by -rollback_end .
@*
Excluded disk_path parameters of extraction commands cause SORRY events.
Implicitely given paths in trees under disk_path parameters are excluded
silently.
@*
If disk file objects already exist then the settings of -overwrite and
-reassure apply. But -overwrite "on" only triggers the behavior
of -overwrite "nondir". I.e. directories cannot be deleted.
