[New-bugs-announce] [issue29968] Document that no characters are allowed to proceed \ in explicit line joining

[Jim Fasarakis-Hilliard]

New submission from Jim Fasarakis-Hilliard:

After looking through the code, the tokenizer only allows a new line character to proceed `\` in explicit line joining [1].

The Devguide section on it [2] actually states many of the limitations of using `\` but not directly that nothing is allowed after it (it does have a remark on comments). 

Would it be a good idea to amend it to state that no characters are allowed after `\`?
