Backslash appears to be supported. To test I used the following test document:
```
foo ~bar~\& baz
```
This happens in a document in worg:
https://git.sr.ht/~bzg/worg/tree/ae64e1a54185232d4ebdcab174d8d4319ffd564d/org-release-notes.org#L6666
The ampersand was chosen for the test document since that is not a supported
POST character, to make sure backslash was not simply escaping the next
character.
In the documentation I wrote out the word "backslash" in parenthesis to
disambiguate between backslash and escaping the following comma.
Patch is attached.
