Window settings applied too late

[gegoune]

Hey, so when I run :PackerSync (or similar) with open_cmd = 'tab new [packer] I get new tab window and for few moments before it gets filled in with plugins list local windows settings are not yet applied.

I know that because I have signcolumn=yes:2 and at the start header's line is off by two characters and wraps to next line.

I think

packer.nvim/lua/packer/display.lua

Line 821 in 3fdea07

make_header(disp)

is the line that draws horizontal line in header, and settings get applied here:

packer.nvim/lua/packer/display.lua

Line 721 in 3fdea07

'setlocal buftype=nofile bufhidden=wipe nobuflisted nolist noswapfile nowrap nospell nonumber norelativenumber nofoldenable signcolumn=no',

.

Could applying of those setting be moved to before anything gets drawn in that buffer?
