shell-command misinterprets multi-line conditional and

[Kevin Rodgers]

shell-command misinterprets a multi-line conditional and command as a background
command:

M-! echo foo && C-q C-j echo bar

executes "echo foo &", which displays "foo\n" in *Async Shell Command*
(instead of "echo foo &&\necho bar", which should display "foo\nbar\n"
in *Shell Command Output*).  The problem is this regexp in simple.el:

          (if (string-match "[ \t]*&[ \t]*$" command)
              ;; Command ending with ampersand means asynchronous.

I think "$" should instead be "\\'", to match the end of the command.
