Fix an issue whereby ANSI escape characters could appear in search output when a pager was not configured. The root cause of the problem was code that was overzealously applying an underlying effect to search terms. This commit simply rips out underlying entirely, both as means of resolving this problem, and also simply for removing needless visual noise from search output.
