master 4b25ffd: Fix "grep foo bar" in eshell

[Lars Ingebrigtsen]

branch: master
commit 4b25ffd3b8ffb854c2458efc4914829ead9a0f79
Author: Lars Ingebrigtsen <larsi@gnus.org>
Commit: Lars Ingebrigtsen <larsi@gnus.org>

    Fix "grep foo bar" in eshell
    
    * lisp/eshell/em-unix.el (eshell-grep): Use the -H switch so that
    we always get the file name, so that `M-x next-error' and friends
    work (bug#22330).
