I fixed this by enclosing the next char lookup code into
a loop over filestack.  Patch attached.

Karl, unfortunately this only applies to @ref/@pxref/@xref,
though I guess it would be useful in other cases as well.

As a general fix (or rather precaution), should I change
execute_string in a way that its local input_text includes
a part of the global input_text, but processing stops as
soon as it reaches the end of its original input_text?

Appended text will not affect the execution, but lookups
like input_text[input_text_offset+1] etc. will work even
at macro (and perhaps @include) boundaries.

Thanks,
