No space when replacing `\copydoc` by `\copydetails`

In case we have something like (taken loosely from issue #4554):
```
- \subpage id_201201031218 \copydoc id_201201031218
```
this would be translated into:
```
- @subpage id_201201031218\copydetails id_201201031218]
```
and subsequently the first word of the `\copydetails` part is placed directly to the `id_201201031218` resulting in an unknown id like `id_201201031218this`

(This actual case it doesn't make much sense to use a `\copydoc` but this can happen in other cases as well).
