Not sure we need the word 'category' in here? and usually diagnostics are all lower case, I think? (though maybe `error: error 'Invalid encoding in DW_AT_decl_file' occurred 4 time(s).` is a bit hard to parse.. (perhaps these shouldn't be printed as errors? It is a bit weird having a whole multiline report each prefixed with `error:`, maybe?) (though it also shows these diagnostics don't follow the lowercase habit either... which is unfortunate))
