Unfortunately, this seems to be a documented limitation of Vim. From the linebreak documentation (an option that causes line breaks in a line for each character):
This option is not used when the 'wrap' option is disabled or the list is enabled.
Alternative solution: select the end of the line. A simple one-time way would be to simply look for them (/ $). Alternatively, you can use the backlight:
:highlight endofline ctermbg=Green :match endofline /$/
This will give you green EOL backgrounds. For more information on how you can highlight a selection, see :help highlight-args .
Original answer
This is not the actual OP problem, but it can sometimes happen, so I will leave it here so that others can find when they are searching.
Using 'list' :
Note that list mode also affects formatting (set using "textwidth" or "wrapmargin") when "cpoptions" includes "L". See "Listchars" for changing the way tabs are displayed.
Using 'cpoptions' :
L When the “list” parameter is set, “wrapmargin”, “textwidth”, “softtabstop” and Virtual Replace mode (see | gR |) are counted as two characters instead of the usual behavior of a.
'cpoptions' is all about vi compatibility - do you run vim like vi ? Or do you manually set any of these flags? Check the output of echo &cpoptions , be sure to run it as vim , and if it is still installed (I don’t know why it would be), you can disable the flag ( set cpoptions-=L ).
And of course, make sure the settings for wrap , wrapmargin , linebreak and textwidth are what you want.
