Get-Error: Avoid duplicate information contained in nested ErrorRecord blocks #11123
Description
Summary of the new feature/enhancement
Update: The issue is primarily that a nested ErrorRecord: prints duplicate information, which results in "noisy" output that is hard to parse; see the discussion in the comments.
Currently, when Get-Error pretty-prints an error, the information about the error record's .Exception and Exception.InnerException values are pretty far apart.
It would be helpful if they were grouped together in the output.
Currently (look for <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< markers; note that in this simple example the messages happen to be the same, but that's not typical):
Exception :
ErrorRecord :
Exception : <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
