reversability issue in inspect.lua from luvit

reduction:

local function escape(str)
	return (str:gsub("\\", "\\\\"):gsub("(%c)%f[0-9]", longControlCharEscapes):gsub("%c", shortControlCharEscapes))
end

with a 100 column width limit, running stylua 0.14.2 on the file twice has an effect. without the 100 column limit (defaulting to 120), it also has unstable formatting on the second format, but it doesn't reverse like it does at the 100 column limit.
