No, return type should be bool, I have changed the same in attached patch.

You are right, I have changed code as per your suggestion.

I think, it gets freed in writefile() in below code.
for (line = lines; *line != NULL; line++)
{
if (fputs(*line, out_file) < 0)
{
fprintf(stderr, _("%s: could not write file \"%s\": %s\n"),
progname, path, strerror(errno));
exit_nicely();
}
free(*line);
}
