I'd like a way to hide/collapse/combine all the file/module/line data that gets printed out in the warnings summary. For larger projects with spaghetti code, it's quite possible this print out ends up being hundreds of lines long.
The same happens when I try to use the "once" action for filter warnings. Which kind of makes sense. That warning is still only being shown 'once'.

Makes sense.
Note that there is some collapsing being done for "SKIPPED", but it could be improved in general also (e.g. with regard to providing an option to collapse / collapsing similar skips via/from different source lines).
So this should likely be looked at / refactored when doing it for warnings then.

Perhaps makes sense to collapse automatically with the default verbosity, and keep the existing display with
-vor greater?
