I'm taking the liberty of "extending" this bug to include a somewhat
related issue. I suppose that's bad practice, but it'll allow us to roll
the original request into the fix without much hassle.

From Emacs -Q:

1. M-x erc RET localhost RET RET RET RET
2. /ignore foo RET
3. Hit RET to forgo adding a timer (doesn't impact result)
4. /unignore fool RET ; note the trailing "l"
5. Answer "y" when asked whether to remove "foo"
6. /ignore RET
7. Notice "foo" is still listed and still appears in `erc-ignore-list'

The attached patch tries to address this issue as well as the original
UX problem regarding rustic timeout handling, with ideas borrowed from
Alcor's gist shared on the emacs-erc list.

Not to keep harping on this, but I'd much rather we rewrite the ignore
and lurker stuff completely and move it to a new module in a new file.
Anyone feeling up to the challenge, please step forward. Thanks.
