* Overlapping sprintf, improve handling of casts
If there is a cast of the argument buffer, cppcheck would print out the
expression including the cast, which looks a bit strange to talk about
Variable (char*)buf is used as...
Instead, only print the variable name without the cast.
Also, handle arbitrary many casts (the previous code only handled one).
Multiple casts of the input arguments is probably an unusual case in
real code, but can perhaps occur if macros are used.
* Fix printing of variable
... and add a test.
