multiline properties are not supported

[brempusz]

According to properties format documentation https://docs.oracle.com/javase/6/docs/api/java/util/Properties.html this should be loaded as one property:

 fruits                           apple, banana, pear, \
                                  cantaloupe, watermelon, \
                                  kiwi, mango

but instead it is loaded as

fruits = apple, banana, pear,
cantaloupe, = watermelon,
kiwi, = mango
