(ls-lisp-support-shell-wildcards): New variable.

(ls-lisp-support-shell-wildcards): New variable.
(insert-directory): Convert the filename wildcard to an equivalent
Emacs regexp, when `ls-lisp-support-shell-wildcards' is non-nil.
Handle file patterns like "/foo*/" as if it were "/foo*", like the
shell would.  Print zero total for files whose total size is
exactly zero (in particular, for no files at all).  Say "No match"
when no files match the given wildcard.
(ls-lisp-format): Make directory listing format more like POSIX ls.
