# 2. Check if current word is a global option; if so, propose completion.
# 3. Check for the presence of a main command (qdisc|class|filter|...). If
# there is one, first call _tc_direct_complete to see if previous word is
# waiting for a particular completion. If so, propose completion and exit.
# 4. Extract main command and -- if available -- its subcommand
# (add|delete|show|...).
# 5. Propose completion based on main and sub- command in use. Additional
# functions may be called for qdiscs, classes or filter options.
