The earlier one would have been usable for reporting an error while
writing any file, but the caller must hold a lock file on it with a
new one. Would this change warrant a renaming of the function, I
wonder.
It is a file-scope static, so all callers know about how they are
supposed to call it, hence the keeping the original name would be
OK, I would think.
This hunk triggered my smello-meter, primarily because "write-error"
would not be the name I would pick for this function if I were
writing everything in this file from scratch (before or after this
particular patch).
