Hi there. I discovered that under certain conditions, show-paren-mode
will highlight the entire left margin of the window when one of the
parentheses is located at the beginning of a line. If you do "M-x
eval-buffer" on the following code, it will reproduce the issue in
emacs -Q (in both the terminal and GUI):

    (linum-mode)
    (custom-set-faces
      '(linum ((t (:foreground "black" :weight bold)))))
    (show-paren-mode)

It happens when linum-mode (or nlinum-mode) is active, but only if the
'linum face has been customized. Attached is a screenshot
demonstrating the overzealous highlighting.
