I've just seen this (old) post, and I was wondering if we could the same thing using GitHub flavoured markdown: Combine the normal syntax highlighting with the diff
one.
I tried a few things, like
```python&diff
- import that
+ import this
```
```python
- import that
+ import this
```
```pythondiff
- import that
+ import this
```
```diffpython
- import that
+ import this
```
But none of them worked... So, do any of you know how to do this? Or it's not possible?
