#   Tests that variables in actions get expanded but double quote characters
# get treated as regular characters and not string literal delimiters when
# determining string tokens concatenated to the variable being expanded.
#
#   We also take care to make this test work correctly when run using both
# Windows and Unix echo command variant. That is why we add the extra single
# quotes around the text being echoed - they will make the double quotes be
# displayed as regular characters in both cases but will be displayed
# themselves only when using the Windows cmd shell's echo command.
