This turns the prompt sequence from something like:
$ examine changes to foo?
$ record change 1/4 to foo?
$ record change 2/4 to foo?
$ examine changes to bar?
$ record change 4/4 to bar?
into:
$ examine changes to foo?
$ record change 1/3 to foo?
$ record change 2/3 to foo?
$ examine change to bar?
$ record change 3/3 to bar?
203ffed27f86 made this simple test-test.t succeed silently:
$ printf ' $ true' > test-test.t
but did not give a usable .err in this case:
$ printf ' $ false' > test-test.t
The missing LF will now be fixed in the test output and it will thus give a
test failure and a solution in the .err file.
