[Proposal] Can we have "\ ", for use with "\z"?

["Soni \"They/Them\" L." <fakedme@...>]

\z is an absolutely wonderful feature of Lua strings, but having to 
break it with \x20 is mildly annoying. Compare:

      local foo = "USAGE\n\z
                   \x20   description."

with

      local foo = "USAGE\n\z
                   \    description."

So, yeah, it'd be nice to have the latter. It lines up the, well, lines, 
so makes it easier to read when looking through source code. (The other 
option is to bump the \x20 back but uh meh.)
