Improve diff hunk headers when maintaining Emacs

* .gitattributes: Improve diff hunk header support for makefiles,
shell scripts, Ada, C, C++, Objective C, HTML, SHTML, XML, Java,
Perl, PHP, Python, Ruby, and TeX, all of which are used in Emacs
somewhere (sometimes just in test cases).
* autogen.sh: Add regexes for makefiles and shell scripts.
