@imbajin Is it necessary to strictly enforce hard wrap (most diffs are caused by this)?

Alone on its own line?

@imbajin Is it necessary to strictly enforce hard wrap (most diffs are caused by this)?

Currently nope (This is happening due to we lack the max-chars control for *.md files 😿 & IDEA used 100 for default)

But it's hard for new comer/devs to know the background, so the auto wrap occurred now.

Maybe we should update the config(max-length) in hugegraph-style.xml early?

#2525 The problem of adapting the maximum length of markdown files can be solved with this pr

@0x2f2f2f2f u could update with the master branch & revert the markdown line break changes in this pr (restart IDEA if not work)
