Gitea Version: 1.1.0+115-g54f0293f (docker image)

When I go to russross/blackfriday to check markdown syntax, just found gitea cannot use Definition lists

Term
: This is a term

I found that there are two usage of
markdown/markdown.go#L148
markdown/markdown.go#L159

if flags&blackfriday.LIST_TYPE_DEFINITION != 0 {

but markdown.go do not included EXTENSION_DEFINITION_LISTS at extension setup by default
and no way to enable it like EXTENSION_HARD_LINE_BREAK by checking
markdown/markdown.go#L619

setting.Markdown.EnableHardLineBreak

After checking code and compare extension list
https://github.com/russross/blackfriday/blob/master/markdown.go

There still have few extension not enabled
will there any way to let us config to enable them like EnableHardLineBreak? or
are there any concern to not let it enable?
