small change similar to previous commit: in search-list.sml's 'backtrackFull' function, always check if the position is at the correct string before checking if we are at the place where the search should continue

pass regression test by modifying 'SearchList.backtrackRange' function. The modification that worked was swapping two if-statements around: first we check if the string position is 0 (and loop to check the previous string if so); in the else case, we check if the searchPos <= 1 (which signals for us to exit backtracking). Swapping the order of the if-statements means that, when we exit the loop, we always exit with string that is at this position.

change the way we calculate the newCursorIdx when we delete using the 'dk' motion while on the last line. We go to the buffer's last line and find the first column. This more directly expresses what we want and now passes the failing unit test for 'dk'.

fix 'MakeNormalDelete.deleteLineBack' test, which failed because we were using the wrong way to check if cursor is currently at the start of the line. We checked '(endOfLine = cursorIdx) which works in most cases to verify that the current position is a newline, but fails when the cursor is at the last non-newline character of the line. This is fixed by being more precise and calling 'Cursor.isCursorAtStartOfLine' to check directly if the cursor is currently at the end of the line.

rename existing 'MakeNormalDelete.deleteLine' function to 'MakeNormalDelete.deleteLineDown', make 'dj' and 'ydj' commands use the renamed function, and add a new 'MakeNormalDelete.deleteLine' function (which has no implementation yet). We do this because we want to distinguish between 'dd' and 'dj' commands, allowing 'dd' to delete to the end of the file despite any count, while stoppinhg 'dj' from deleting the file when on the last line.
