# The deferred commands are run in the order '.END .BEGIN all'.

# This may be unexpected at first since the natural order would be

# '.BEGIN all .END', but it is implemented correctly.
|
|
#
|
|
# At the point where the commands of a node with deferred commands are run,
|
|
# the deferred commands are appended to the commands of the .END node.
|
|
# This happens in Compat_RunCommand, and to prevent an endless loop, the
|
|
# deferred commands of the .END node itself are not appended to itself.
|
|
# Instead, the deferred commands of the .END node are run as if they were
|
|
# immediate commands.
