subtasks line length is not limited

[joshinils]

writing a subtask is not limited by the amount of characters entered.
this could pose a potential issue where one enters too many, and the whole menu displaying it is so large that the delete button gets pushed outside the visible area on the right.

you could implement the same logic where a line gets broken when it is too long that the description os a task itself has.

i would appreciate it if this line-width is configurable via the settings
