Fix string pattern for type-2 git status -z entries

[rami3l]

Closes #1157.

Tested with the example from #1157 (comment):

-- NEW!
local match_2 = "(.)(.) (....) (%d+) (%d+) (%d+) (%w+) (%w+) (%a%d+) (.+)%z(.+)" 

local rest = "R. N... 100644 100644 100644 ac01e6941fe11104afee78fa73ad77f9707d169b ac01e6941fe11104afee78fa73ad77f9707d169b R100 lua/plugins/lsp/rust-analyzer.lua\0lua/plugins/lsp/rust_analyzer.lua"
local mode_staged, mode_unstaged, _, _, _, _, _, _, _, name, orig_name = rest:match(match_2)

print(orig_name) -- lua/plugins/lsp/rust_analyzer.lua
print(name)      -- lua/plugins/lsp/rust-analyzer.lua

Great find :D

@CKolkey Oops, the quick fix looks problematic... Sorry I'm still new to Lua and Neovim 🙇

Somehow the pattern matching fails completely now. Maybe we are not capturing '\0' in rest?

[CKolkey]

No worries, did a revert and will poke it later :)

Seems that it gets the wrong unstaged information with this commit.

So, the underlying issue is that the null character is converted to a newline:

{ "# branch.oid dab4e50be18eab8f337b908cd871ab5f4dd031d3", "# branch.head master", "# branch.upstream origin/master", "# branch.ab +0 -0", "2 R. N... 100644 100644 100644 09c1b7ad1d5

LICENSE2 \n LICENSE. If you grep for stdout_raw you'll find a few other workarounds for this newline thing. It's... slightly annoying, and possibly a self-own.

Alright, sorted it out. Thanks again for tracking down the source of the issue :)
