Configuring text export block output

[Tim Quelch]

Hi all,

Is there a way to configure how text is exported in ascii?

For example if I have a source block

#+begin_src python
Some code here
with multiple lines
#+end_src

With `org-ascii-export-as-ascii` the above block gives:

,----
| Some code here
| with multiple lines
`----

I don't really like this as the '|' at the start of the lines make it
annoying to copy and paste. Is there a way to configure the export to
give something surrounded by backticks?

```python
Some code here
with multiple lines
```

I've had a look into the available `org-ascii-*` customise variables and
I couldn't see anything which looked to give this functionality.
Preferably I'd love a way if I could configure this locally and
programatically, as in some contexts I might still want the "prettier"
output of the default, but in other contexts I might want the more
"practical" output of backticks.

Side question: Perhaps what I am wanting can be achieved with markdown
export, however it seems that the default markdown exporter exports code
indented. This has the same problem of being frustrating to copy-paste.
Is there a way to configure the md exporter to use fenced code blocks?

Thanks,
