The file path must be relative to the repository's
working folder and must be readable.
This method will fail in bare index instances.
This forces the file to be added to the index, not looking
at gitignore rules. Those rules can be evaluated through
the git_status APIs (in status.h) before calling this.
If this file currently is the result of a merge conflict, this
file will no longer be marked as conflicting. The data about
the conflict will be moved to the "resolve undo" (REUC) section.
