Fix/noeol (#295)

* Handle missing EOL in todo.txt

This can happen easily with certain editors (such as Mousepad) that do not automatically add a newline character at the end of a file.
In _addto(), ensure a trailing newline via sed (taken from https://unix.stackexchange.com/a/31955/18876).

Fixes #294

* Tests: Add basic coverage of move

* Handle missing EOL in todo.txt for move, too

This can happen easily with certain editors (such as Mousepad) that do not automatically add a newline character at the end of a file.

* Refactoring: Extract fixMissingEndOfLine()

* FIX: Compatibility: sed \+ multi not supported on MacOS

Use the POSIX \{1,\} instead.
