[Emacs-diffs] master 6eac401: Make ielm accept an optional buffer name param

[Bozhidar Batsov]

branch: master
commit 6eac401c238b9c98550c645f3c60df9a9668dc61

    Make ielm accept an optional buffer name param
    
    The ielm buffer name was hardcoded which made it hard for programs to
    interactively create ielm buffers with different names and switch to
    them (e.g. perhaps you want to have one ielm buffer for each of the
    Elisp projects you're working on).
