Bug#956881: enchant: Keep out of bullseye

[Reuben Thomas]

Upstream Enchant maintainer (and DM) here! I'm delighted to see the
transition is happening; if there are any problems with Enchant 2, I'm very
happy to help. I am not sure which Debian notifications I get about
Enchant, so if I seem to overlook something that could use my attention,
feel free to ping me directly.
