*g:netrw_errorlvl*		=0: error levels greater than or equal to
				    this are permitted to be displayed
				    0: notes
				    1: warnings
				    2: errors

  *g:netrw_fastbrowse*		=0: slow speed directory browsing;
				    never re-uses directory listings;
				    always obtains directory listings.
				=1: medium speed directory browsing;
				    re-use directory listings only
				    when remote directory browsing.
				    (default value)
				=2: fast directory browsing;
				    only obtains directory listings when the
				    directory hasn't been seen before
				    (or |netrw-ctrl-l| is used).

				Fast browsing retains old directory listing
				buffers so that they don't need to be
				re-acquired.  This feature is especially
				important for remote browsing.  However, if
				a file is introduced or deleted into or from
				such directories, the old directory buffer
				becomes out-of-date.  One may always refresh
				such a directory listing with |netrw-ctrl-l|.
				This option gives the user the choice of
				trading off accuracy (ie. up-to-date listing)
				versus speed.

  *g:netrw_ffkeep*		(default: doesn't exist)
				If this variable exists and is zero, then
				netrw will not do a save and restore for
				|'fileformat'|.

  *g:netrw_fname_escape*	=' ?&;%'
				Used on filenames before remote reading/writing

  *g:netrw_ftp_browse_reject*	ftp can produce a number of errors and warnings
				that can show up as "directories" and "files"
				in the listing.  This pattern is used to
				remove such embedded messages.  By default its
				value is:
				 '^total\s\+\d\+$\|
				 ^Trying\s\+\d\+.*$\|
				 ^KERBEROS_V\d rejected\|
				 ^Security extensions not\|
				 No such file\|
				 : connect to address [0-9a-fA-F:]*
				 : No route to host$'

  *g:netrw_ftp_list_cmd*	options for passing along to ftp for directory
				listing.  Defaults:
				 unix or g:netrw_cygwin set: : "ls -lF"
				 otherwise                     "dir"


  *g:netrw_ftp_sizelist_cmd*	options for passing along to ftp for directory
				listing, sorted by size of file.
				Defaults:
				 unix or g:netrw_cygwin set: : "ls -slF"
				 otherwise                     "dir"

  *g:netrw_ftp_timelist_cmd*	options for passing along to ftp for directory
				listing, sorted by time of last modification.
				Defaults:
				 unix or g:netrw_cygwin set: : "ls -tlF"
				 otherwise                     "dir"

  *g:netrw_glob_escape*		='[]*?`{~$'  (unix)
				='[]*?`{$'  (windows
				These characters in directory names are
				escaped before applying glob()

  *g:netrw_hide*		Controlled by the "a" map (see |netrw-a|)
				=0 : show all
				=1 : show not-hidden files
				=2 : show hidden files only
				 default: =1

  *g:netrw_home*		The home directory for where bookmarks and
				history are saved (as .netrwbook and
				.netrwhist).
				Netrw uses |expand()| on the string.
				 default: stdpath("data") (see |stdpath()|)

  *g:netrw_keepdir*		=1 (default) keep current directory immune from
				   the browsing directory.
				=0 keep the current directory the same as the
				   browsing directory.
				The current browsing directory is contained in
				b:netrw_curdir (also see |netrw-cd|)

  *g:netrw_keepj*		="keepj" (default) netrw attempts to keep the
				         |:jumps| table unaffected.
				=""      netrw will not use |:keepjumps| with
					 exceptions only for the
					 saving/restoration of position.

  *g:netrw_list_cmd*		command for listing remote directories
				 default: (if ssh is executable)
				          "ssh HOSTNAME ls -FLa"

  *g:netrw_list_cmd_options*	If this variable exists, then its contents are
				appended to the g:netrw_list_cmd.  For
				example, use "2>/dev/null" to get rid of banner
				messages on unix systems.


  *g:netrw_liststyle*		Set the default listing style:
                                = 0: thin listing (one file per line)
                                = 1: long listing (one file per line with time
				     stamp information and file size)
