Error message for "edit-task" not accurate

[lerxcl]

If I typed a wrong attribute such as "start", it also tells me that "Index is not a positive integer.", which might not be very helpful in this case. However, it is good that the parameters were being included at the last line, so that the user can see what attribute he/she wanted to type, like "to:" instead of "start:".

Same error message if i type "s", even though the index "6" is a valid index.

• I disagree

Reason for disagreement: Even if the edit command code is mostly the same as AB3, the context has changed from "contacts" to "task", and the parameters to edit a task is different from a contact.

Thus, the error handling should be adapted for the new parameters.
