[pass] Concurrency issue with --clip

[Von Welch]

My $0.02 after reading all of this is that clearing the clipboard instead
of restoring it makes the most sense.

Having some sort of lock file so that if you quickly (<45 sec apart) run
'pass -c' multiple times, only the last invocation clears the clipboard
might make sense or might be harder than it is worth.
