underline in YAML files about zenburn HOT 1 CLOSED

No, it's not - it seems to map to lo<Label> which is indeed underlined and does not look so nice.

It's a bit tricky to fix properly since Vim loads the color file at startup and then the colors just linger around. The color scheme is not checked at every file open.

If you work predominantly on YAML files, you might want to use let g:zenburn_disable_Label_underline=1 to avoid the underline.

Alternatively, to target YAML files only, do this in your .vimrc:

autocmd FileType yaml highlight! def link yamlBlockCollectionItemStart NONE
