It was essentially copy-on-write. However, with the logic simplification of the previous commit, this case was eliminated and the strbuf is always populated. Directly use the strbufs now instead of an alias. Since this already changes all the lines that use the strbufs, rename them from `uq` to be more descriptive. That they are unquoted is not their most important property, so name them after what they carry. Additionally, `file_change_m` no longer needs to copy the path before reading inline data.
