🐛 Updating bat cache with new theme crashes delta

[aaharr]

Hi Folks,

After adding a .thTheme to bat and rebuilding its cache, no delta calls work.

Seems related to https://github.com/dandavison/delta/issues/1304. I also installed with brew.

thread 'main' panicked at library/alloc/src/raw_vec.rs:571:5:

Installing with cargo gives similar output.

Deb install wants me to upgrade libc6 which seems too risky for today.. (on Ubuntu focal)

Installing a newer version of Bat seems to have resolved this issue (0.24.0) (via binary release). Also a temporary way to get out of the bad state is to delete the offending bat cache.

Looks like the version of bat in apt is quite old (0.12..) might be good to throw an error right away if it's a broken version 🙌
