Fix two line wrapping bugs in default report formatter

The first is that the ANSI escape codes applied to bold the message when
`-s` is used were not being taken into account when wrapping the lines
for width, causing some lines to be wrapped unnecessarily.

The second is that when lines were wrapped in the middle of a long
message, the `|` characters making up the table were being bolded along
with the message.
