Should GIT_EDITOR and GIT_SEQUENCE_EDITOR have quoted values?

I was checking git hooks and noticed that GIT_EDITOR and GIT_SEQUENCE_EDITOR for post-checkout hook during rebase contain quoted path to lazygit, so they are not printed by env to be:

```env
GIT_SEQUENCE_EDITOR=/opt/local/bin/lazygit
GIT_EDITOR=/opt/local/bin/lazygit
```

but rather:

```env
GIT_SEQUENCE_EDITOR="/opt/local/bin/lazygit"
GIT_EDITOR="/opt/local/bin/lazygit"
```

Is this correct behaviour?

Start with the post-checkout hook during rebase and inspect how GIT_EDITOR and GIT_SEQUENCE_EDITOR are set before checking their values with env. Compare the quoted and unquoted forms, then establish whether the behavior is intentional; done means resolving the question with the appropriate behavior verified.
