Using the cleaninput function, to escape &'s on certain actions.
Currently the actions needing escaped &'s are append, prepend and replace.
Other actions including add need unescaped &'s.
Set $TODO_SH to just be $(basename "$0") at the beginning
of the script and use it in all usage messages.
This happens to simplify testing because it allows us to refer to
the script as "todo.sh" in all output. For general use, if the
user has aliased to file to something else, the usage messages will
still reflect that alias.

Add a test_todo_session function to test-lib.sh that enables
easy recording of input and output from todo.sh (including
annotation of exit status for testing error cases).
Begin to port and re-factor testsuite.txt into smaller
test cases, starting with basic add list functionality
and replace functionality.
Thanks to Philippe Teuwen <phil@teuwen.org> for feedback
