magit next, revision b84af7c
Sometimes magit gets confused and thinks that point is on a diff instead of on a file. This happens to me when I want to ignore files (both with "i" and "I").
Steps to reproduce:
I suppose "Can't ignore a tracked file" would be a better message. (You can't, you know. Even if it's added to .gitignore manually, the fact that it's tracked overrides the ignore rule.)
Good point -- I've actually stumbled over this myself. However, I've used "git rm said_file" afterwards. Maybe instead of showing a completely wrong error message something like "File is already under version control; remove and ignore? yes/no" would be appropriate.
