[PATCH 1/2] am: pay attention to user-defined context size

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

am previously only checked gpg-related config options and the default
config options while ignoring any diff-related options.  This meant that
when users tried to set diff.context to something larger than the
default value of 3, it was ignored.  Pay attention to the diff settings
too.

In combination with commit 09ac67a1839e ("format-patch: move
git_config() before repo_init_revisions()", 2019-12-09), which is part
of the dl/format-patch-notes-config-fixup topic, this fixes
   git -c diff.context=5 rebase
to actually use five lines of context.
