Markdown: fenced code block within block quote loses quotes after one line

When there is a fenced code block (the lines sandwiched between the lines of the three backslashes) is placed in a block quote (a block of lines where each line starts with a block quote marker '> ' ) as in:

> quoted block
> ```
> code line 1
> code line 2
> code line 3
> ```
> fenced block ended above
>

The block quote ended above.

only the first line of of the fenced lines retains the block quote marker after extraction and merge. All lines after the first line of the fenced block lose the marker including the lines after the fenced block.

> quoted block
> ```
> code line 1
code line 2
code line 3
```
fenced block ended above


The block quote ended above.

To reproduce, use the attached quoted-fenced-block.md:

    ./tikal.sh -x quoted-fenced-block.md

    ./tikal.sh -m quoted-fenced-block.md.xlf

The resulting quoted-fenced-block.md.out.md doesn't have the block quote marker after the first line of the fenced block.

A error message "Something's not right in block quote...." is observed on both runs of tikal.sh.
