The phrase "File ended" implies that the end of the file in
question was reached which is not the case in the scenario
pointed out by me.

That's why I suggested:

! Processing the file ended while scanning definition of \foobar.

This phrase does not imply a reason for ending the processing
of the file and therefore might be less misleading in situations
like the scenario pointed out by me and might cover more
situations correctly.
