If you use the paredit minor mode in emacs lisp mode buffers, then M-"
paredit-doublequote will double the backquotes.

Unfortunately, since | is an escape character in lisp, if you paste a
shell pipe with an odd number of | in elisp, select it and M-", it will
signal an Unbalanced parentheses error and not do the work. 

Instead you can add a | at the end to make an even number of them,
select the shell expression and type M-".


C-y               echo foo.bar | sed -e s/\..//
|                 echo foo.bar | sed -e s/\..//|
C-SPC C-a        [echo foo.bar | sed -e s/\..//|]
M-"              "echo foo.bar | sed -e s/\\..//|"
C-e C-b DEL      "echo foo.bar | sed -e s/\\..//"


In any case, you should always use paredit-mode for lisp editing.
