About adding newline to end of worktodo file

[valeriob01]

# Command breakdown:
    # '.' denotes any character *except* newline
    # '$' denotes the end of file
    # 'a\' appends the following text (which is nothing, in this case) on a new line
    # In other words, if the last line contains a character that is not newline,
    # append a newline.

    sed -e '/.$/a\' "$@"
