Backtraces in logs are bad unless Logging is loaded

[KristofferC]

With REPL not being in the sysimage we have the following:

# 1.10
❯ julia -e '@warn "beep" exception=(ErrorException("foo"), backtrace())'
┌ Warning: beep
│   exception =
│    foo
│    Stacktrace:
│     [1] backtrace()
│       @ Base ./error.jl:114
│     [2] macro expansion
│       @ logging.jl:373 [inlined]
│     [3] top-level scope
│       @ none:382

└ @ Main none:1

It doesn't really make sense to me why the REPL should be required to print things nicely to stdout. Those two things seem like orthogonal concepts.

It isn't REPL, but the broken state of logging if using Logging isn't present:

$ ./julia -e '@warn "beep" exception=(ErrorException("foo"), backtrace())'
┌ Warning: beep
│   exception = (ErrorException("foo"), Union{Ptr{Nothing}, Base.InterpreterIP}[Ptr{Nothing} @0x00007f5726afd3a0, Ptr{Nothing} @0x00007f573ad32c6b, Ptr{Nothing} @0x00007f573ad56b9b, Ptr{Nothing} @0x00007f573ad563da, Ptr{Nothing} @0x00007f573ad576b5, Ptr{Nothing} @0x00007f573ad57d78, Ptr{Nothing} @0x00007f573ad59575, Base.InterpreterIP in top-level CodeInfo for Main at statement 50, Ptr{Nothing} @0x00007f573ad7d7a2, Ptr{Nothing} @0x00007f573ad7e160, Ptr{Nothing} @0x00007f573ad80202, Ptr{Nothing} @0x00007f5726c752c4, Ptr{Nothing} @0x00007f5726d95da8, Ptr{Nothing} @0x00007f5727157b90, Ptr{Nothing} @0x00007f573ad32c6b, Ptr{Nothing} @0x00007f573adbeb15, Ptr{Nothing} @0x00007f573adbf631, Ptr{Nothing} @0x0000562c9300c08c, Ptr{Nothing} @0x00007f573b9efd8f, Ptr{Nothing} @0x00007f573b9efe3f, Ptr{Nothing} @0x0000562c9300c0c4])

Ah,

julia/stdlib/Logging/src/Logging.jl

Lines 142 to 144 in ba34d89

	function __init__()
	global_logger(ConsoleLogger())
	end

So, move ConsoleLogger to Base? What's the point of the Logging stdlib anyway?
