# git abbreviation with 'g' prefix, 7+ hexadecimal digits
#
# From git 2.11.0 changelog:
# The default abbreviation length, which has historically been 7, now
#   scales as the repository grows, using the approximate number of
#   objects in the repository and a bit of math around the birthday
#   paradox.  The logic suggests to use 12 hexdigits for the Linux
#   kernel, and 9 to 10 for Git itself.
