my dumb mistake

[Joshua N Pritikin]

To create a new password entry for "foo," I typed "pass edit foo" in one 
terminal window. Then I forgot and entered the same thing in another 
terminal window. I closed them in the wrong order and wiped out my 
changes.

At the beginning of "pass edit foo", would it be possible to snapshot 
the previous version of the file? Then if the file didn't match it's 
snapshot, the user could be warned.

Maybe there is a race condition here, but better to have a safety check 
that usually works than no safety check.
