      You're right, I was not paying attention. It was selecting the last character, which was the underscore and the boundary was the
      following character. If you do your test with a space following the underscore, you will see what I mean.

      You're absolutely right. I had taken John by his word and not tested
      this.

      In the text

      aaabbbccc
      aaa bbbccc aaabbb ccc aaa bbb ccc
      aaa_bbbccc aaabbb_ccc aaa_bbb_ccc
      aaa _bbb ccc aaa bbb_ ccc aaa _bbb_ ccc
      aaa_ bbb_ccc aaa_bbb _ccc aaa_ bbb _ccc

      the pattern "\bbbb\b" (b was a bad letter choice in hindsight) matches
      the last string in the second and in the fifth line, nothing else.
