Use parameter expansion of variables within heredoc
Thanks to Quentin Rameau and Thomas Oltmann for remarking that the
workaround $(printf $VARIABLE) was not one of my brightest ideas, given
you can just use ${VARIABLE} instead.
Additionally, make use of an $ANTISUFFIX variable in the
next_break-template.
