Further to this: If a runtime (non-syntax) error occurs, it is
correctly reported. This is handled by fstring_fix_node_location in
ast.c, which adjusts the reported locations so future error handling
gets things right. But that happens *after* any syntax errors get
reported, which happens in pythonrun.c inside err_input(), I think.
That doesn't get adjusted to the main file's locations, so it gets
reported as "<fstring>" line 1.
