It contains the hashes of the parent *objects*: typically it refers to
the last time that the file was modified.

But a patch often depends on more recent changes made in *other* files,
for example when calling a function of another class that was recently
implemented or changed.

So there is a loss of information when creating a patch with git
format-patch, at least with the default parameters.
