I don't care particularly. What about an underscore?

So I remove it and effectively in FF there is no space beween the input HTML element and the question text.
echo "<input $style $readonly $popup name=\"$inputname\"";

However as cloze is used sometimes to ask for a punctiation mark, we should not add anything.

Do you agree?

I'm sorry, I don't understand. What is FF? It's actually short-answer (type in the text) question types that I'm particularly bothered about.

So what was the question?

I cannot add another field to fill when editing because there is no provision for this in cloze syntax.

I think that the best way to do it is to withdraw the space and let the authors (teachers) add it if they want so.

This could change the display of actual questions but does not add more difficulty to the students as the input box is clearly defined.
Although some can argue that some students will want to add a space in their responses. In this case the manual grading can be used .

I propose to withdraw the space.

Help file should clearly specify this.
