ls quoting style change requires Emacs tramp pkg update

[Bob Givan]

Emacs 26 provides the following bug fix to Emacs 25:

https://github.com/emacs-mirror/emacs/commit/e4adb6

which fixes the dired/tramp/ls interaction bug introduced by the "new" quoting style in ls:

https://lists.gnu.org/archive/html/bug-coreutils/2016-03/msg00032.html

Because 18.04 LTS provides Emacs25 without this fix, BUT provides ls with the new quoting-style default, Emacs dired-mode breaks when used over tramp, if filenames and directories contain spaces.

The easy bug fix above should be retroactively applied to the version of Emacs/tramp that is being provided. Alternatively, Emacs 26 could be provided, or Tramp updated to 2.3.2 provided within Emacs25.

Specifically, remote directories listed using dired over tramp show files and directories (those with spaces in the names) that cannot be acted upon by dired commands but instead complain that the listing is out of date and needs updating, even if updated.

The two line fix cited above resolves the problem in my installation.
