That explains the implementation bug, I guess.
But there's no backquote or comma here.
And `@@@@@@' is just a normal symbol.
Just as we don't treat comma the same inside
and outside backquote (we raise an error for
the latter), ideally we shouldn't treat @ the
same inside and outside backquote (symbol
syntax for the latter).
And presumably the only uses of @ inside
backquote that should lead to different
indentation would only be when @ follows
comma.
