Subject: [PATCH] fix below zero message count check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

size_t is unsigned and hence can't be below zero, triggering this gcc
warning with gcc 10:
  warning: comparison of unsigned expression in ‘< 0’ is always false [-Wtype-limits]

It seems this if statement is meant to check if there are messages to
process (larger than 0). If there are no messages, we should jump out
early.
