The issue with with terminal handling of escape sequences, rather than with git. If you are concerned, you can use a gui diff tool, or you can pipe it through a filter that removes escape codes: seal:~/work/gitPocDiff$ cat > uncolor #!/usr/bin/env perl ## uncolor — remove terminal escape sequences such as color changes while (<>) { s/ \e[ #%()*+\-.\/]. | (?:\e\[|\x9b) [ -?]* [@-~] | # CSI ...
