This is a minor priority enhancement request.

This is a small program:


///
void foo(char c = '\n') {}
///
void bar(char c = '\r') {}
void main() {}



If I compile it with -D it generates an HTML file that contains:

...
<dl><dt><big><a name="foo"></a>void <u>foo</u>(char <i>c</i> = '\x0a');
</big></dt>
<dd><br><br>
</dd>
<dt><big><a name="bar"></a>void <u>bar</u>(char <i>c</i> = '\x0d');
...


I suggest to show '\n' and '\r' there, to make the documentation more similar to the original code and a little more readable.

For an example of it see the online HTML documentation of std.stdio.byLine:

auto byLine(Terminator = char, Char = char)(KeepTerminator keepTerminator = KeepTerminator.no, Terminator terminator = '\x0a') if (isScalarType!Terminator);
