Re: [PATCH v3 3/4] builtin/verify-tag: move verification code to tag.c

> The PGP verification routine for tags could be accessed by other
> commands that require it. We do this by moving it to the common tag.c
> code. We rename the verify_tag() function to pgp_verify_tag() to avoid
> conflicts with the mktag.c function.
