#
# $2 - the current token, also accessible by $__arg from the above scope -
# basically a private copy of $__arg; the token can be eg.: "grep"
#
# $3 - a private copy of $_start_pos, i.e. the position of the token in the
# command line buffer, used to add region_highlight entry (see man),
# because Zsh colorizes by *ranges* in command line buffer
#
# $4 - a private copy of $_end_pos from the above scope
