[O] [ANN] Allow filled inline src blocks and Babel calls

[Nicolas Goaziou]

Hello,

It is now possible to fill inline babel calls and inline source blocks.
Code within an inline source block is always treated as a single line,
tho.

This improvement required quite a few internal changes to Babel. Nothing
bad can happen, right? In any case... please report anything suspicious
in that area.


Regards,
