gt> Append '\n' to the formatted string before return. If you write it
gt> to the (manifest) file, it will ensure file ends with a newline.
gt>
gt> Many GNU utilities have problems processing the last line of a file
gt> if it is not '\n' terminated. E.g. if the last line is not terminated
gt> by a newline character, then "read" will read it but return false,
gt> leaving the broken partial line in the read variable(s).
gt> It can also break or adversely affect some text processing tools,
gt> that operate on the file.

Reworked in v2. Now it is built.
