+core.abbrevguard::
+ Even though git makes sure that it uses enough hexdigits to show
+ an abbreviated object name unambiguously, as more objects are
+ added to the repository over time, a short name that used to be
+ unique will stop being unique. Git uses this many extra hexdigits
+ that are more than necessary to make the object name currently
+ unique, in the hope that its output will stay unique a bit longer.
+ Defaults to 0.
