Miscounting of lines in case of fenced code block

When we have an example like:
~~~
Page
=======

test text
test text \error1

```
make
```

```
make
```

test text \error2
~~~
we get the warnings:
```
aa.md:5: warning: Found unknown command '\error1'
aa.md:17: warning: Found unknown command '\error2'
```
instead of
```
aa.md:5: warning: Found unknown command '\error1'
aa.md:15: warning: Found unknown command '\error2'
```
this is due to the fact that there are 2 returns in case of a fenced code block, one with the ``endcode` but with the detection of the fenced code block (`isFencedCodeBlock`) it is not "removed".
