The following code:
----------------------------------------

void delegate(int a) dg;

/// Test - this works
void delegate(int b) dg2;

/// Test - this doesn't
void delegate(int c)[] dg3;

/// Another test - this doesn't either
void delegate(int d)* dg4;

void main() {}

----------------------------------------
Produces the following DDoc output for the symbol 'dg2':

    void delegate(int b) dg2; 
        Test - this works

    void delegate(int a)[] dg3; 
        Test - this doesn't

    void delegate(int a)* dg4; 
        Another test - this doesn't either

Notice how the name of the first parameter is wrong when the delegate is part
of a composite type (dg3 and dg4). It does not happen when the variable is of
plain delegate type (as is the case of dg2). It seems to happen even in cases
when dg is in an imported module.

I don't know if this is a regression - if it is, it's not a recent one. I
tested on versions 2.060, 2.059, 2.058 and 2.057; they all exhibit the exact
same problem.
