Inline Edit - caret position when entering edit mode

[Justin]

In the inline-edit simple text story boards (http://wiki.fluidproject.org/display/fluid/Inline+Edit+Storyboard+-+Allow+user+to+edit+simple+text 
) there are several examples given.

The first case states that when the field enters into edit mode, all  
of the text should be selected.

The second case states that the caret should be at the end of the text.

The third case doesn't mention where the caret or selection should be  
but shows the caret in the middle of the text. This seems to imply  
that the caret should be placed where the user clicks on the field to  
put it into edit mode.

I'm not sure which one of these is/should be correct. Are these  
supposed to indicate three different ways that the inline edit field  
will behave based on context? If that is the case, would it be  
confusing for the user, as all three could theoretically be on the  
same page?
