provided with local files i.e. colorized symlinks, executables files
etc... whereas using `helm-list-dir-lisp' will allow colorizing only
directories but is more portable.
NOTE: `helm-list-dir-external' needs ls and awk as dependencies.
Also the ls version installed on the remote side should support the
same arguments as the GNU/ls version that are -A -1 -F -b and -Q.
So even if you are using a GNU/ls version locally and you want to
connect e.g. on a Freebsd server you may have failures due to the
incompatible ls version installed on remote server.
In such case use `helm-list-dir-lisp' which work everywhere but is
slower and less featured (only directories colorized)."
