Another use of "@"?

Hi,

My setup is a bit peculiar where I do git development on three different machines. Say I updated branch long-branch-name on machine A. Then I continue my work on machine B. I would want to hard reset that long-branch-name on machine B before resuming my work. What I usually do is

git co long-branch-name git diff A/long-branch-name git reset --hard A/long-branch-name

but typing long-branch-name (even with TAB completion) is not fun. Could I do this (or something similar) instead?

git co long-branch-name git diff A/@ git reset --hard A/@ -- Duy
