I'm unable to reproduce this error in 9.1.rc0. Might depend upon the
editor, OS version, Sage version, position of stars.
It still shows some weirdness:

sage: attach("bug.sage")
sage: 2+2

### reloading attached file bug.sage modified at 01:27:20 ###
sage: 2+2
^[[43;1R4

- note the junk printed after the 2nd "2+2".
