Add Word Count to last Text Frame in chain for Filler Text

[GarryP]

I think it might be useful if, when using Filler Text (see note below), the last frame of the chained Text Frames displayed the word count, see attached image (word count not exact, just a mock-up).
This would be helpful in situations where the writer, editor and layout artist wanted to be fairly sure that the text will fit into the layout.
For example:
* Editor tells the writer to produce, say, 1000 words;
* Editor tells the layout artist to use a certain layout;
* Layout artist creates the layout and uses filler text while the copy is being prepared;
* Layout artist notices that the text frames will either probably not hold the prescribed number of words or will probably leave a big gap;
* Layout artist advises the editor;
* Editor tells the writer to either cut their copy down to fit or write more copy.
This may allow the layout artist and writer to be able to reasonably ensure that the copy which is submitted is nearer to the required length earlier in the production process and, therefore, lessen problems later on when deadlines are nearer.
This isn’t a major thing for me – I probably won’t use it at all personally – but I think some people might benefit.

Note: I am not requesting that this word count is provided for non-Filler Text, this is just for when Filler Text is used. (A word count for ‘normal’ text has been discussed elsewhere and I don’t want to go over all that again.)
