[PATCH 0/3] Better support for customising context lines in --patch commands

["Leon Michalak via GitGitGadget" <gitgitgadget@gmail.com>]

This series of patches attempt to give --interactive/--patch compatible
builtins ("add", "commit", "checkout", "reset", "restore" and "stash")
better support and nicer experience for configuring how many context lines
are shown in diffs through a variety of ways.

Prior to these patches, the user could not choose how many context lines
they saw in --patch commands (apart from one workaround by using
GIT_DIFF_OPTS=-u<number> ..., however this isn't a good user experience or a
persistent solution). Additionally, the behaviour around reading from the
diff.context and diff.interHunkContext configs was also inconsistent with
other diff generating commands such as "log -p".

The summarised changes below hopefully make this experience better and fix
some inconsistencies:

 * diff.context and diff.interHunkContext configs are now respected by
   --patch compatible commands
 * --unified and --inter-hunk-context command line options have been added
   to --patch compatible commands (which take prescendence over file
   configs)
 * "add" and "commit" in --interactive mode now expose a new "context"
   subcommand which configures the amount of context lines you wish to see
   in subsequent diffs generated from other subcommands such as "patch" or
   "diff"
