--appimage-help exceeds 80 characters

--appimage-extract text is too long, does not fit into the standard window width of many terminals

A fancier solution would involve reading the terminal's width and formatting the strings accordingly. But that would be overkill.

What about something like this:

            "AppImage options:\n\n"
            "  --appimage-extract [<pattern>]\n"
            "           Extract content from embedded filesystem image\n"
            "           If pattern is passed, only extract matching files\n"
            "  --appimage-help                 Print this help\n"
            "  --appimage-mount                \n"
            "           Mount embedded filesystem image and print\n"
            "           mount point and wait for kill with Ctrl-C\n"
            "  --appimage-offset               Print byte offset to start of embedded\n"
            "                                  filesystem image\n"
