Re: A puzzle: reset --hard and hard links

My suspicion is that Git keeps a cache of the stat(...) result of
files. An additional hard link increases the .st_nlink count of this
struct. `git reset` compares the cached stat(...) values to the actual
ones and sees that one has changed. `git status` does the same but is
smart enough to realize that the additional hard link does not change
anything. It writes this to the cache. `git reset` should also be
smart!

See the core.trustctime config.
