have to remove the help lines that begin with `#` in the commit log
template yourself, if you do this).
+commit.gpgsign::
+
+ A boolean to specify whether all commits should be GPG signed.
+ Use of this option when doing operations such as rebase can
+ result in a large number of commits being signed. It may be
+ convenient to use an agent to avoid typing your GPG passphrase
+ several times.
+
commit.status::
A boolean to enable/disable inclusion of status information in the
commit message template when using an editor to prepare the commit
--auto` consolidates them into one larger pack. The
default value is 50. Setting this to 0 disables it.
+ gc.autodetach::
+ Make `git gc --auto` return immediately andrun in background
+ if the system supports it. Default is true.
+
gc.packrefs::
Running `git pack-refs` in a repository renders it
unclonable by Git versions prior to 1.5.1.2 over dumb
Common unit suffixes of 'k', 'm', or 'g' are
supported.
+pack.useBitmaps::
+ When true, git will use pack bitmaps (if available) when packing
+ to stdout (e.g., during the server side of a fetch). Defaults to
+ true. You should not generally need to turn this off unless
+ you are debugging pack bitmaps.
+
+pack.writebitmaps::
+ When true, git will write a bitmap index when packing all
+ objects to disk (e.g., when `git repack -a` is run). This
+ index can speed up the "counting objects" phase of subsequent
+ packs created for clones and fetches, at the cost of some disk
+ space and extra time spent on the initial repack. Defaults to
+ false.
+
+pack.writeBitmapHashCache::
+ When true, git will include a "hash cache" section in the bitmap
+ index (if one is written). This cache can be used to feed git's
+ delta heuristics, potentially leading to better deltas between
+ bitmapped and non-bitmapped objects (e.g., when serving a fetch
+ between an older, bitmapped pack and objects that have been
+ pushed since the last gc). The downside is that it consumes 4
+ bytes per object of disk space, and that JGit's bitmap
+ implementation does not understand it, causing it to complain if
+ Git and JGit are used on the same repository. Defaults to false.
+
pager.<cmd>::
If the value is boolean, turns on or off pagination of the
output of a particular Git subcommand when writing to a tty.
Note that an alias with the same name as a built-in format
will be silently ignored.
+pull.ff::
+ By default, Git does not create an extra merge commit when merging
+ a commit that is a descendant of the current commit. Instead, the
+ tip of the current branch is fast-forwarded. When set to `false`,
+ this variable tells Git to create an extra merge commit in such
+ a case (equivalent to giving the `--no-ff` option from the command
+ line). When set to `only`, only such fast-forward merges are
+ allowed (equivalent to giving the `--ff-only` option from the
+ command line).
+
pull.rebase::
When true, rebase branches on top of the fetched branch, instead
of merging the default branch from the default remote when "git
