Oh yeah...

Perhaps hiding those spaces behind a helper variable e.g.
'dump_term_clear_line=Q<80-spaces>Q' and embedding that in the here
docs specifying the expected output in these three tests could make it
ever so slightly less yuck...

'test-lib.sh' sets TERM=dumb relatively early on, and in these tests
we don't use 'test_terminal' to run 'git rebase', so...  yeah.  And
term_columns() defaults to 80.

However, if the terminal were smart, then we would have to deal with
ANSI escape suddenly popping up...
