|

# - :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".
|
|
# Mainly used to detect premature termination of commands.
|
|
#
|
|
# The tokens are always added with both leading and trailing colons to serve as
|
|
# word delimiters (an improvised array); [[ $x == *:foo:* ]] and x=${x//:foo:/}

|
# the current state --- that is, the value of $this_word --- for two iterations
|

# (one for the redirection operator, one for the word following it representing
|
|
# 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.
|
|
#
|
|
# The "the previous word was a redirection operator" state is not communicated
|
|
# to the next iteration via $next_word/$this_word as usual, but via
|
|
# $in_redirection. The value of $next_word from the iteration that processed
|
|
# the operator is discarded.
