Unfold continuation lines. Prepend every line that ends with a "" character to the next line. Remove any leading blanks from the continuation line.

Consider the following file:

    $ cat example.txt
      This is a \
        continuation line.
    But these
      are not.

unfoldcon reads from stdin en writes to stdout:

    $ cat example.txt | unfoldcon
      This is a continuation line.
    But these
      are not.
