Provide method for clearing errors in buffer. #698
Description
It can be difficult to read code, especially large regions of code, that have an error overlay applied. AFAIK, Emacs does not provide a command for removing overlays, so one needs to M-: (delete-all-overlays) RET to remove the error. This is a hassle. I've currently bound this procedure to C-x C-M-e:
(defun cider-clear-errors ()
(interactive)
(delete-all-overlays))

That's a bit too extreme (as it will delete unrelated overlays). A proper solution would be:
Guess we can wrap this in an interactive command.

Are you talking about the compilation error message? If so it's only one in the whole buffer and #690 deletes it once you modify the region. I have been using it for a day now and it feels pretty right. Alternatively it can be deleted when the pointer enters the error region or on a timeout. I am a bit inclined towards deleting it on entering. I will try it today.

It turns out that
point-enteredhook is a text and not an overlay property. So sorry, it's too complicated.As we are on it, I think CIDER should blink the region when jumping to an error and don't leave an overlay at all. This is precisely how comilation in emacs works (see
next-error-highlight). Unfortunately cider is not quite integrated with emacs next-error functionality. I plan to look more comprehensively into this issue at the end of the week.
