branch: master
commit 181e92c4e060a7ce4740b561375f9ec9f473f144
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>
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.
