# git-mv-with-history -- move/rename file or folder, with history. | |
# | |

# utility is best explained from the kernel wiki: | |
# | |
# Git has a rename command git mv, but that is just for convenience. | |
# The effect is indistinguishable from removing the file and adding another | |
# with different name and the same content. |
