I wrap, but not religiously, and in particular I don't wrap diffs, and
I set 'list' on because I want to see several of the 'listchars'
options, including a visible end-of-line, visible tabs and visible
no-break spaces. So I also customize 'listchars' in my vimrc.
The way I understand it, and the way it's documented, 'listchars' is
used in two cases:
a) to display ordinary editfile text when 'list' is on
b) to display the output of the :list command.
AFAIR it has been like this since before I started using Vim.
Most of the possible 'listchars' settings have a defaut which means
that, when omitted, that particular setting will default to what Vim
does when 'list' is off, with at least one exception: the hard tab.
When 'list' is off, a hard tab is displayed as one or more spaces
until the next character is at an abscissa which (if the first
position in a line is 1) is one more than a multiple of 'tabstop'.
When 'list' is on and 'listchars' does not include "tab:", a hard tab
is represented by the two characters ^I. To get the default behaviour
with 'list' on (and for instance some other nondefault setting) you
need
:set lcs+=tab:\ \
i.e. two backslash-escaped spaces. (I use tab:\|_ which is stored as
|_ and gives one vertical bar plus zero or more underscores.)
If you want to see precedes and extends, and default the rest, you may use
:set list lcs=tab:\ \ ,extends:>,precedes:<
IIUC this should give you the same behaviour as with 'nolist' except
that long lines will have a < at the left margin and/or a > at the
right margin depending on which part of the line is displayed. Of
course, if you prefer other characters, the choice is unlimited. With
'encodiing' set to utf-8 (and, I suppose, a "scriptencoding utf-8"
statement near the top of your utf8-encoded vimrc), another possible
setting would be
:set list lcs=tab:\ \ ,extends:→,precedes:←
Or you may (like me) go whole hog and use
if exists('+list')
set list
if exists('+listchars')
set lcs=eol:¶,tab:\|_,extends:>,precedes:<,conceal:*,nbsp:·
endif
endif
Best regards,
Tony.
