Fix two line wrapping bugs in default report formatter

[anomiex]

Description

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.

Suggested changelog entry

• Avoid unnecessarily wrapping lines in the full report when -s is used.
• Fix incorrect bolding of pipes in the full report tables when -s is used and messages wrap.
