Extra safety when unreading alignment-related characters for \aligned #2384

Closed dginev closed 3 months ago

Fixes #2383 . Quite subtle, but I think I got it - I can make the minimal example from the issue into a test if preferred.

Details: The key problem was that when the ->unread of a { happened, the actual aligned state got modified, rather than the "safely neutralized" local state, which appears to be the primary purpose of this parameter type.

Your observations seem right, and this patch doesn't cause any surprises that I can detect. Thanks!
