[Mesa-dev] [PATCH 4/9] bin/get-pick-list.sh: handle the fixes tag

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

Having a separate script to handle the fixes tag, brings a number of
issues, so let's fold it in get-pick-list.sh.

v2:
 - pass the sha as argument to the function
 - Keep original sed pattern
