# POSIX sh has no 'var+=' so 'var=${var}append' is used. What's
# interesting is that 'var+=' _is_ supported inside '$(())'
# (arithmetic) though there's no support for 'var++/var--'.
#
# There is also no $'\n' to add a "literal"(?) newline to the
# string. The simplest workaround being to break the line inside
# the string (though this has the caveat of breaking indentation).
