Support posting images with no caption

[gaaruru]

Using a command in the form tweet.sh tw -i image.png Hello world will successfully post the image and caption, but tweet.sh tw -i image.png causes the script to hang indefinitely for me, when I would expect it to post the image with no caption. It also hangs when sending a space, like " ".

It seems like the problem can be solved by not putting the word status in the params variable in post() if there are no more params to follow status. Images seem to work with or without captions by including the word status in posting_body():

posting_body() {
  if [ "$*" != '' ]; then
    echo -n -e "status $*" | sed -E -e 's/$/\\n/' | paste -s -d '\0' -
  fi
}

and removing the word status from post():

$(posting_body $*)

That way, the word status is not sent if there is no status/caption.
But I'm not a shell expert so I don't know if this snippet would cause other problems.

Thanks!

The commit 1672de7 allows you to post images without text, like as:

$ echo '' | ./tweet.sh tw -i ~/photos/1.jpg

Please note that you still need to give a blank text via the STDIN (echo '' | ...), otherwise it will hang up.

Update: with more commits 6eceaea , 68ef7f2 , and 92ed1ee, now you can post images without any blank input like:

$ ./tweet.sh tw -i ~/photos/1.jpg
