Code highlighting.

In case we have an example like (based on issue #7302):
```
/// @file
/// Something

template <char C>
struct one { };

/// The struct single_009 the char
struct single_009 : one<'       '> { };
/// The struct single_010 the char

struct single_039 : one<'\''> { };
/// The struct single_040 the char (
struct single_040 : one<'('> { };
/// The struct single_041 the char )
struct single_041 : one<')'> { };
/// The struct single_042 the char *
struct single_042 : one<'*'> { };

struct single_058 : one<':'> { };
/// The struct single_059 the char ;
struct single_059 : one<';'> { };
/// The struct single_060 the char <
struct single_060 : one<'<'> { };
/// The struct single_061 the char =
struct single_061 : one<'='> { };
/// The struct single_062 the char >
struct single_062 : one<'>'> { };
/// The struct single_063 the char ?
struct single_063 : one<'?'> { };
```
The result is that in the code section there are no links to the structs 41, 61, 62 as the `(` and `<` block it till the corresponding `)` and `>` is found.
Analogous problem for the double quote version.
