           Summary: wrong string literals in "cannot pass argument" errors
           Product: D
           Version: D2

I've noticed this bug when reading this forum post:
https://forum.dlang.org/post/rjdgoaoowxgvekraktwx@forum.dlang.org

Code:
----
void f(int x) {}
void main()
{
    f("%i");
}
----

The error message says (DMD 2.086.0):
----
test.d(4):        cannot pass argument "1" of type string to parameter int x
----

Instead it should say:
----
test.d(4):        cannot pass argument "%i" of type string to parameter int x
----

With `f("%s");` DMD even segfaults.

Fix incoming.
