Incorrect width calculated in MTTextArea

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start by adding any string to the widget when 'autosize' or 'autowidth' has 
been specified.
2. Replace the entire string with '\n' or ''
3. Check the reported width.

What is the expected output? What do you see instead?
The width of the string should be reported as 1.0 but it is reported as the 
maximum width of any line in the previous string. This happens because 
'recalc_size' does not recalculate the width if the first or only line in the 
string is empty

What version of the product are you using? On what operating system?
v0.5.1-dev running on Ubuntu 10.04
