Yes, it does assume you don't change the file name. Maybe we can extend 
it somehow to follow file name changes that git know about... that might 
be a good idea!

However, I think it's perfectly reasonable to work with the current 
assumptions. It is clear that pass cannot know anything about the 
history of a password before you imported it from another password 
manager (for example). I am using it to rotate my passwords every now 
and then and for that it suffices.

By the way: my patch is actually looking at the first line of the file, 
not at the timestamps of the files.

Keeping a time stamp together with a password is probably not such a 
good idea because sooner or later the two *will* get out of sync.

Which wording can I improve? Do you mean the term "age" or are you 
referring to Steffen's "last change" or maybe my cmd_usage text?
