Long assertion messages corrupt the formatted output

[prantlf]

Assertions like t.ok(value, message) can be passed messages longer than usual terminal width. For example:

TAP version 13
# Exported dependency names can be resolved.
ok 1 The dependency "csui" should be resolvable.
ok 2 The dependency "esoc" should be resolvable.
# Resolving an unknown dependency fails.
ok 3 The message "Unrecognised dependency: "dummy"." should start with "Unrecognised dependency:".

1..3
# tests 3
# pass  3

# ok

The output appears to print the assertion message on two lines and when the test name is going to be printed, it ends up at the beginning of the first line too. For example:

✓ Exported dependency names can be resolved.
# Resolving an unknown dependency fails.
✓ Resolving an unknown dependency fails.ncy: "dummy"." should start with "Unre# tests 3
# pass  3
✓ ok

The expected output should contain only the test names:

✓ Exported dependency names can be resolved.
✓ Resolving an unknown dependency fails.
# pass  3
✓ ok
