[Option] /format [Description] 
Specifies the formats of summarizing merge conflicts: Brief: default value, summarizes only the total number of conflicts, warnings, and errors. Detailed: summarizes not only the total number of conflicts, warnings, and errors but also lists details about each conflict.
