[Bug]: Formatting with missing END causes deletion of a space in next function declaration

[steinhh]

Current Behavior

This file is formatted correctly:

FUNCTION test
  FOREACH a, [1, 2, 3] DO BEGIN
    print, a
  END
END

PRO test
  test
END

but when deleting the first END and typing save with format-on-save active, the file becomes:

FUNCTION test
  FOREACH a, [1, 2, 3] DO BEGIN
    print, a
  END

  PROtest
  test
END

The formatting can obviously not become correct with incorrect code, but the space between PRO and test should not have been deleted.

Expected Behavior

Expected behaviour would be to complain about a syntax error, without formatting the file.
