# State machine
#
# The states are:
# - :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".
# 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:/}
# will DTRT regardless of how many elements or repetitions $x has..
