closing quote does not always end escaping of text

[Oliver Joos]

Without option -T (--textual) any text containing double letters should be escaped using quotes. Otherwise double letters become filled areas.

With aafigure 0.3 if the ending quote is followed by a non-space character then escaping not always ends.

This does not work:
+-------+
|"Hello"| o--->
+-------+

Working workaround:
+--------+
|"Hello" | o--->
+--------+
