If the text to be appended to the task begins with one of the delimiter characters, no whitespace is inserted in between. This makes appending to an enumeration (todo.sh add 42 ", foo") syntactically correct.
The list of delimiters is configurable (for personal preferences / non-English languages) via SENTENCE_DELIMITERS in the config file.
- _list() now shows the capitalized filename in place of 'TODO:'.
For example, listing garden.txt produces a output prefixed by 'GARDEN:'
This eliminates the ' from $FILE' part of the _list() output. All tests
were adjusted to match this new output.
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.
