Title: fix issue 8272 [Ddoc] Recursive macro expansion is failed.

The reason why recursive macro expansion was failed is because it was given escapes by 0xff7b and 0xff7d where expanding '$1'.
It is necessary to remove this escape to enable recursive macro expansion.
The adverse effects by removing this were not confirmed in test case and the documentation of some projects that I owned.
