rendering bug in code blocks

[rsubr]

On Perlite v1.6, any code block that has the following syntax is rendered incorrectly. This bug is present regardless of the code block type (text, python, php, sh, bash, yaml, etc).

Input

```
[[ foo | bar ]]
```

Output

bar

This breaks any embedded shell script, YAML, etc.

More examples:

Input

```
until [[ -n grep -hs ^ sites/common_site_config.json | jq -r ".db_host // empty" ]] &&
[[ -n `grep -hs ^ sites/common_site_config.json | jq -r ".redis_cache // empty"` ]] &&
[[ -n `grep -hs ^ sites/common_site_config.json | jq -r ".redis_queue // empty"` ]];
```

Output incorrectly rendered:

        until  jq -r ".db_host // empty"`  && \
           jq -r ".redis_cache // empty"`  && \
           jq -r ".redis_queue // empty"` ;

Fix

Used Google Antigravity to vibe code fix perlite/content.php. Preliminary code review looks good to me and all my test cases are passing.

content-php.patch

Thanks @secure-77 as always, pls include this in the next release.

I can confirm this bug and unfortunately it effects more then only your example as I have done some more regex-based post processing in the content.php. I am currently working on bigger redesign to move all of the processing into the Parsedown engine.

Most of the work is already done but it needs some more tests, however if you want you can already try the latest DEV build, which should fix your issue.
