Regression in displaying of stacktraces with recursive functions.

[KristofferC]

It seems a lot of the niceness that has been added for "stackoverflow type" of errors (or just generally when a function is called recursively) has been lost:

As an example:

julia> f(x) = g(x)
f (generic function with 1 method)

julia> g(x) = f(x)
g (generic function with 1 method)

1.7:

julia> f(10)
ERROR: StackOverflowError:
Stacktrace:
     [1] f(x::Int64)
       @ Main ./REPL[1]:1
     [2] g(x::Int64)
       @ Main ./REPL[2]:1
--- the last 2 lines are repeated 39990 more times ---
 [79983] f(x::Int64)
       @ Main ./REPL[1]:1

1.8+:

julia> f(10)
ERROR: StackOverflowError:
Stacktrace:
 [1] g(x::Int64)
   @ Main ./REPL[2]:1
 [2] f(x::Int64)
   @ Main ./REPL[1]:1

The

--- the last 2 lines are repeated 39990 more times ---
 [79983] f(x::Int64)

part is lost.

---

Another example:

julia> f(x) = f(x)
f (generic function with 1 method)

1.7:

julia> f(1)
ERROR: StackOverflowError:
Stacktrace:
 [1] f(x::Int64) (repeats 79984 times)
   @ Main ./REPL[1]:1

1.8:

julia> f(1)
ERROR: StackOverflowError:
Stacktrace:
 [1] f(x::Int64) (repeats 2 times)
   @ Main ./REPL[4]:1

1.8 says repeats 2 times which seems wrong..

I have the correct (full) error message for both cases on 1.8.5, 1.9.3, 1.10 and master so this is probably system specific. My system is

so this is probably system specific

I guess so, too. Both cases work fine for me on v1.6~v1.10 and master.

Adding to this, It would be nice if the (repeats $n times) warning was at least emphasized / printed in color: https://github.com/JuliaLang/julia/blob/ec321703c89f0aeed1805008d6f33545ec279852/base/errorshow.jl#L765
