if 'MakeNormalDelete.deleteLine' deletes to the end of the file such that there is no newline at the end, then append a newline. This makes one of the tests we have pass.

|
add a new failing test, and modify 'TestUtils.init' function (which takes a string and returns an AppType.app_type) so that it does not automatically add a newline to the end of strings. (This modification required changing the strings in some tests, as those strings did not have newlines at the end but the test assumes they did.)

in text builders, check when on newline if this is the second last character in the file, and draw it on a newline if so. This is to align with the design decision that we want the second-last character to be selectable

amend very minor bug: when looping through DFA and hitting a 'final state', we let the next chr afterwards handle the start state, but we want the current char to handle the start state instead, as this matches vim's behaviour

|
handle edge case when deleting by DFA: when we are deleting to the end of the file and if cursor is on first character after newline, then we also want to delete preceding newline too. Or else we will end up with two newlines at the end of the file, which is not what we want.
