Why does get(handles.editbox, 'String') return a char when the box is empty but a cell for all other cases?

Is this expected behavior or is it a bug?
I finally tracked down a frustrating bug to this behavior, as I was tacking the contents of several edit boxes onto the end of a cell array.
I worked around by writing my own getEditboxContents function that always returns a cell, but that seems like it shouldn't be necessary.
What is the best practice for handling this case?
Cheers

Nicholas - I suspect that this is expected behaviour. If the edit box control allows for multiple lines (because the Max property is greater than the Min property), then the return of
get(handles.edit1,'String')
would be an mx1 cell array where m is the number of lines in the edit box. That's why, whenever I call the above on edit boxes which are single lines, I always wrap the get in a char
char(get(handles.edit1,'String'))
so that the result is in fact a string (or char array).
