maint: Improve default diff hunk header detection.
Tell git where to look for diff hunk headers: top-level definitions for
Scheme files, and (sub)section headers for texi files.

* .gitattributes, etc/git/gitconfig: New files.
* doc/contributing.texi ("Submitting Patches"): Add subsection
"Configuring Git".  Document etc/git/gitconfig.

+If you have not done so already, you may wish to set a name and email
+that will be associated with your commits (@pxref{telling git your name,
+, Telling Git your name, git, Git User Manual}).  If you wish to use a
+different name or email just for commits in this respository, you can
+use @command{git config --local}, or edit @file{.git/config} in the
+repository instead of @file{~/.gitconfig}.
+
+We provide some default settings in @file{etc/git/gitconfig} which
+modify how patches are generated, making them easier to read and apply.
+These settings can be applied by manually copying them to
+@file{.git/config} in your checkout, or by telling Git to include the
+whole file:
+
+@example
+git config --local include.path ../etc/git/gitconfig
+@end example
+
+From then on, any changes to @file{etc/git/gitconfig} would
+automatically take effect.
+
+Since the first patch in a series must be sent separately
+(@pxref{Sending a Patch Series}), it can also be helpful to tell
+@command{git format-patch} to handle the e-mail threading instead of
+@command{git send-email}:
+
+@example
+git config --local format.thread shallow
+git config --local sendemail.thread no
+@end example
