"clear e" command confirmation does not follow specification in help message displayed to user

[brianchoon]

First, I entered the command clear e, intending to clear all events.

I was met with this prompt to confirm.

However, when I typed "Y", it proceeded to clear all events as well.

I believe this is a functionality bug because the user typed a string other than "y" (which is "Y") and the command executed.

It may be wise to tell the user that either "y" or "Y" triggers the confirmation.

Side note: This problem also appears when running the clear p command.
