You're misreading what I'm saying, it's the other way around. fzf doesn't support line wrapping very long lines.
I have really long commands in my shell history and fzf just truncates them, which makes it pretty useless in many cases, since those commands are similar or identical up to 80-100-120 characters.
So in many situations I kind of have to guess which command has the parameter that I want at the end.
It's not that my shell history has lines with line wrap in them, it's that fzf can't show long commands on multiple lines so that I can see the entire command...
