nil value errors when there are no listed buffers

[cseickel]

If I don't set hide_when_one_buffer = true, and I open nvim without a file, I get errors about nil values and cokeline fails to load properly. I use Startify and normally open nvim without arguments and then launch a session from Startify (which is an unlisted buffer) so I hit that every time.

Here is the error I get: E5108: Error executing lua ...ack/packer/start/cokeline.nvim/lua/cokeline/cokeline.lua:83: attempt to perform arithmetic on field 'width' (a nil value)

I worked around the issue by adding this check to _G.cokeline() in init.lua:

... 

function _G.cokeline() 
    state.buffers = buffers.get_listed(state.order) 
    if #state.buffers < 1 then
        opt.showtabline = 0
        return
    end

...

I'm not sure if that's the ideal solution for everyone or not, but it works for me.

Actually, that solution is not good because it disabled the tabline permanently. A better workaround is to return an empty string just before the cokeline:render function if there are no listed buffers.

c430ab62d7038adae282935558f5962d989c3715 should fix this. Could you test it?

That is working perfectly now, thanks!
