The output of git-reflog(1) is currently only customisable by calling
reflog with --pretty=... or overriding the "pretty.oneline" format in
the config, which is currently the default fallback.
To enhance flexibility and save typing, teach reflog to fall back to a
default format specified in the config option "reflog.pretty" unless a
different pretty format is given on the command line. This behaviour is
similar to the "format.pretty" option for git-log(1) and git-show(1).
When "reflog.pretty" is not set, fall back to the old default of
--pretty=oneline --abbrev-hash.
