When I'm using emacs-shell, I often try to run files for which a backup (with ~ ending) exists.
I use Helm, and if I try to auto-complete the name of a file called, say, seed-rand.rb, with an existing backup, I get a result like the image below:
completion-at-point really isn't helping me here—is there any way of telling it to ignore files ending with ~? (That's what it does when helm-mode is turned off.)
And if that's not possible, is there any way of just turning this helm feature off without toggling helm-mode every time I want to do so?

@xuchunyang solved this (see the comments section):
"When the global minor mode helm-mode is off (it is by default), the behavior of completion-at-point will not be changed by helm at all. If you want to turn on helm-mode and don't want it to change completion-at-point, customize user option helm-completing-read-handlers-alist."
I had success when performing this solution via M-x customize.

helm-modedisabled. Also, note that the function used to compute the completion candidates istags-completion-at-point-functionin both cases, so we shouldn't expect any difference either.C-h cto ask Emacs which function is running when I hit<tab>, it returnscompletion-at-point? Is that the wrong way to figure out the function that runs?helm-modeshould only affect how the completion candidates are displayed --- not what they are. This is the behavior I observe when trying to reproduce your problem.helm-modeis off (it is by default), the behavior ofcompletion-at-pointwill not be changed by helm at all. If you want to turn onhelm-modeand don't want it to changecompletion-at-point, customize user optionhelm-completing-read-handlers-alist.
