core.exception.RangeError@std.conv(2526): Range violation

Unittests in std.conv don't test wstring and big numbers.

Also I think, it's an overkill to fine tune allocation as it's done in to!string(uint)

BTW I just improved optimization by adding preallocated strings for numbers between -1 and -9.

The bug is in line 2526 where Char.sizeof * maxlength is allocated but only maxlength is sliced for the buffer.
