In a git-rebase-todo file, parsing for comment syntax is incomplete. Not all comments have correct syntax highlighting.

Original vscode issue

Inside git-rebase-todo files, there is no syntax highlighting for # comments

Steps to Reproduce:

1. Ensure clean git status
2. Create an empty commit git commit -m "asdf" --allow-empty
3. Start interactive rebase git rebase -i HEAD~1
4. Note the line with pick 809y2e3 asdf ends with # empty. This is a code comment in this file.
5. Add a line to the git-rebase-todo file:
6. exec echo 'asdf' # comment
7. Close file, to begin rebasing.
8. Observe that the echo 'asdf' prints a plain asdf and the # comment does not interfere at all.

If you scroll to the bottom of a git-rebase-todo file, you'll see a large block of comments created by git, a guide for doing the interactive rebase. Note that these comments are green (I'm using vscode's default dark theme)
