#
# 1. We use "{" as the delimiter, which lets us skip to the reflog
# date specifier as our second field, and then our "-n" numeric
# sort ignores the bits after the timestamp.
#
# 2. POSIX leaves undefined whether this is a stable sort or not. So
# we use "-k 1" to ensure that we see HEAD before master before
# side when breaking ties.
