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