Doxygen: Backticks (`) in Doxygen-markup-in-C in Markdown collapses

[wataash]

Describe the bug

This markdown file:

good:

```c
/**
 * @c good
 */
int a;
```

bad:

```c
/**
 * `bad`
 */
int b;
```

end

will be rendered into a collapsed-look:

Expected behavior

`bad` becomes like \c good

To Reproduce

mkdir test/

cat > test/test.md << 'EOS'
good:

```c
/**
 * @c good
 */
int a;
```

bad:

```c
/**
 * `bad`
 */
int b;
```

end
EOS

cat > test/Doxyfile << EOS
GENERATE_HTML = YES
GENERATE_LATEX = NO
GENERATE_XML = YES
INPUT=$PWD/test/test.md
XML_OUTPUT=$PWD/test/out/
HTML_OUTPUT=$PWD/test/html/
HTML_FILE_EXTENSION=.xhtml
STRIP_CODE_COMMENTS=NO
EOS

doxygen test/Doxyfile
open test/html/md_test_test.xhtml

Note that this Doxyfile contains STRIP_CODE_COMMENTS=NO to avoid https://github.com/doxygen/doxygen/issues/7793.

In doxygen there are 2 ways to create fenced code blocks in markdown syntax i.e. with tildes and with backticks. In case we need the other character in a fenced block we can easily switch to the other representation, though when both types are needed inside a fenced block we still have the same problem.

The problem also occurs only when the fenced character is the last non blank before the end of line.

I've just pushed a proposed patch, pull request #7797
