I ran into a line in git commit ouput I had not see before #copied: d0/etc/hosts -> misc/old-readerHOSTvcs-files/etc/hosts So googling I learned that this might happen if git thinks the two files are the same. I was pretty sure they were not the same so checked them> <inside git repo> diff d0/etc/host misc/old-readerHOSTvcs-files/etc/hosts The output is a bit long but shows them being quite different. Some 2 dozen or so lines that dramatically differ. Here are two that are at least kind of similar but would never be seen as the same: < 192.168.1.43 m2.local.lan m2 # 00-90-F5-A1-F9-E5 > 192.168.1.43 m2.local.lan m2 # win 7 Not to mention they are quite different lines as well. So what is going on and what should I be looking at?
