# - :start: Command word
|

# - :sudo_opt: A leading-dash option to sudo (such as "-u" or "-i")
|
||||
# - :sudo_arg: The argument to a sudo leading-dash option that takes one,
|
||||
# when given as a separate word; i.e., "foo" in "-u foo" (two
|
||||
# words) but not in "-ufoo" (one word).
|
||||
# - :regular: "Not a command word", and command delimiters are permitted.
|
||||
# Mainly used to detect premature termination of commands.
|
||||
# - :always: The word 'always' in the «{ foo } always { bar }» syntax.
|
||||
#
|
||||
# When the kind of a word is not yet known, $this_word / $next_word may contain
|
||||
# multiple states. For example, after "sudo -i", the next word may be either
|
||||
# another --flag or a command name, hence the state would include both :start:
|
||||
# and :sudo_opt:.
|

#

# the redirection target). Therefore, we set $in_redirection to 2 upon seeing a

# redirection operator, decrement it each iteration, and stall the current state
|
||||
# when it is non-zero. Thus, upon reaching the next word (the one that follows

# the redirection operator and target), $this_word will still contain values

# appropriate for the word immediately following the word that preceded the
|

# redirection operator.
