Resets the TUI cursor color if:
- current 'guicursor' mode does not specify a highlight group
- cursor highlight group has "inverse" or "reverse" flag
- on Nvim exit
We interpret, "inverse" to mean "default cursor".
Example:
hi Cursor guifg=bg guibg=fg
set termguicolors
set guicursor=n-v-c-sm:block,i-ci-ve:ver25-Cursor,r-cr-o:hor20
* When the cursor shape is block, its color will be "inverse"
* When the cursor shape is I-beam, its color will be `hi Cursor`.
This is useful e.g. to prevent `set listchars=eol:¬` causing your cursor
color to a low contrast color in insert mode because you cursor are
often at EOL in insert mode.
