[PATCH v6 3/6] verify-tag: change variable name for readability

[santiago@nyu.edu]

From: Santiago Torres <santiago@nyu.edu>

The run_gpg_verify() function has two variables, size and len.

This may come off as confusing when reading the code.  Clarify which
one pertains to the length of the tag headers by renaming len to
payload_length.
