[PATCH] Bash 3.x completion support

[Graham Lyons]

Hello,

I'm using password-store on OSX (latest, 10.12.6) which comes with Bash
version 3.2.57. I get errors when using the completion as the `compopt`
command doesn't exist before Bash 4. Avoiding use of `compopt` still seems
to allow the completion to work (I'm guessing there's something missing) so
I've prepared a patch which tests for its existence first.

I hope this is in the right format - let me know if there are any problems.

Thanks,
Graham
