Using Viper and toggle-debug-on-error at the same time is irritating
because the debugger is activated on each "Viper bell" signal. This is
solved by adding the signal to debug-ignored-errors. Since Viper's other
common error messages are given a defconst, this patch replaces all
instances of "Viper bell" with a new defconst, viper-ViperBell, and that
defconst is also used for debug-ignored-errors.

Good catch, thanks.
Nowadays these kinds of problems are solved by using `user-error`
instead of `error`. This saves you the trouble of messing with
debug-ignored-errors.
Can you provide an updated patch using that?
Also, while this is sufficiently trivial not to require copyright
paperwork, it gets you closer to this point so it might be a good time
to start the process (IIRC you also have some packages that we could
include in GNU ELPA). For that, please fill the form below and send it
as instructed to the FSF so they can send you the relevant paperwork
to sign.

Oh, duh, that makes a lot more sense. Here's a patch with user-error
instead.
