message is issued with the given severity. Then it depends on the setting
of command -abort_on whether restoring goes on or gets aborted.
@*
Mode "restore_single" tries to set the attribute flags of a file one-by-one
if the attempt fails to set them all at once. This happens only if the
"restore_error=" severity and the setting of command -abort_on do not
demand to abort the program run.
Note that some flags in some situations get ignored silently by some kernels.
@*
Mode "no_restore_single" disables this attempt to get at least some of the
attribute flags into effect.

Mode "default" reinstates the default settings:

-lfa_flags off:read:restore:restore_su_auto:restore_only_known
@*
-lfa_flags restore_mask=:restore_error=sorry
-lfa_flags restore_mask=:restore_error=sorry:restore_single

Use "default:on" to get default settings with enabled processing.
