Unobtrusively highlight column 81 to indicate that we may have to wrap stuff − this is a "soft wrap".
Column 121 is highlighted a bit more obvious, as this is really getting too long!
This is a less obtrusive way of doing "set colorcolumn" (which is just distracting and annoying).
This plugin is extremely simple; almost trivially so. Code for configuration would be more than the actual plugin code.
Simply copy the contents of
plugin/softwrap.vim to your vimrc or fork this
