I was looking today at duplicating a file but, I soon realized that
there is no 'git cp' command (this was the "deductive approach to git
commands", starting from git mv/rm/...). How does "git diff -C" detect
copies (-C is used for this, according to the documentation)?
On a very simple test, I couldn't see this working. I just copied one
file, added it, committed the change, ran "git diff -C HEAD^!". There is
no place saying that it's contents is copied from some other file (both
files are in the repository now).
"git blame -C new_copied_file" also doesn't show the commits for the
original file.
This is all with 1.5.6.1.
I am probably missing something here... but I can't produce an example
of copied contents that actually works. Any hint would be appreciated.
I found this older thread [1] on "git cp" but the discussion appears to
have stalled at some point. If there is indeed no use of a "git cp"
command, I would like at least some info on how content copies are being
detected, since I haven't seen this working.
