Elisp to open a line-wrapped URL

[ckhan]

Say I like wrapping my code at 80cols.
But say I also occasionally include URLs in comments .

So I might wind up with something like this 

    # See also Google Drive generated py docs:
    # https://developers.google.com/resources/api-libraries/
    # documentation/drive/v2/python/latest/
    # drive_v2.permissions.html#insert

How do I teach emacs to open the URL that is near my cursor, even though it's 
split across lines with comment markers in between?
