[erlang-questions] Trim Logger output

Since logger is so new, I don't know about any real use examples, but
since chars_limit
specifically tries to reduce the number of characters to the given number
I'd set it to the actual size (or possibly a bit smaller) that you allow. If
the size is absolute, then I'd use max_size in addition to do the hard

If you'd rather use depth, the outcome is a bit harder to predict, but I
found this guideline in some old documentation:
"A reasonable starting value for Depth is 30. We recommend to test crashing
various processes in your application, examine the logs from the crashes,
and then increase or decrease the value."
