Crash after writing commit mesage (using delta diff)

[DannyJJK]

Describe the bug After finishing a commit message and pressing enter, lazygit crashed. The commit was successful, so perhaps the issue was related to the diff display (I'm using delta). The crash showed the following message:

panic: runtime error: index out of range [0] with length 0

goroutine 140 [running]:

To Reproduce Steps to reproduce the behavior:

To be honest I'm not sure how to replicate it, it happened unexpectedly and I've used lazygit a lot without any issues. Maybe someone else may know?

Expected behavior To complete the commit as normal.
