semi-concatenated strings

[jodoin]

Actually this is not an error in the Parser. It is well documented that you can
do this. In the grammar rules
a string can imediately follow another string.  This rule is specified so that
you will not have to use
as many backslashes. For more information see the Python Language Specification
in section 2.4.2 String Literal concatenation
