bug#16006: 24.3; *grep* fails to display line numbers with global-linum-mode

[Mark Lillibridge <mdl@alum.mit.edu>]

The following should produce a *grep* buffer:

    emacs -q
    M-x global-linum-mode
    ^x^f ~
    M-x grep
    a *

Note that only the first four lines of the *grep* buffer have line
numbers when all the visible lines should have line numbers.  Switching
to the new *grep* buffer dones make the line numbers appear.
