# - :regular: "Not a command word".
# Mainly used to detect premature termination of commands.
#
# 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 tokens are always added with both leading and trailing colons to serve as
# word delimiters (an improvised array); [[ $x == *:foo:* ]] and x=${x//:foo:/}
# will DTRT regardless of how many elements or repetitions $x has..
