I.e. removed the colon after the ITEM#. Updated tasks are now listed like the 'todo.sh ls' command does, e.g.
42 smell the roses
This is in preparation to eventually use a function factored out from _list() for the verbose task output, which would enable coloring in the verbose message and thus align the verbose message output even more with the normal task output.
- Condensing whitespace around TERM into a single space and removing leading/trailing spaces if at the beginning/end of the task.
- Proper error message if TERM not found.
- Aligned verbose removal message with the verbose output of the 'replace' command.
In addition, removed (accidental) printing of the task (without leading ITEM#) when checking for existence of the task; using empty check of task text as done elsewhere.
