If there are overloaded functions, the same anchor ID is generated for all
overloads, making it impossible to link to a specific one.

Example code:

/// First overload
void func() { }

/// Second overload
void func(int x) { }

/// Main
void main() {}

Ddoc output:

<html><head>
        <META http-equiv="content-type" content="text/html; charset=utf-8">
        <title>test</title>
        </head><body>
        <h1>test</h1>
        <!-- Generated by Ddoc from test.d -->
<br><br>
<dl><dt><big><a name="func"></a>void <u>func</u>();
</big></dt>
<dd>First overload<br><br>

</dd>
<dt><big><a name="func"></a>void <u>func</u>(int <i>x</i>);
</big></dt>
<dd>Second overload<br><br>

</dd>
<dt><big><a name="main"></a>void <u>main</u>();
</big></dt>
<dd>Main<br><br>

</dd>
</dl>

--------

Note that overriding the default Ddoc macros does not help, because DDOC_ANCHOR
is only passed the function name, so there is no way to distinguish between
overloads.

Not to mention, this breaks HTML compliance (anchor names are supposed to be
unique).
