.ps files are hardly ever edited any more, so they're low priority. .m4 files 
are more important.  I installed into master the attached patch, which adds 
support for shell, makefiles, m4, and other formats that git already supports 
well. Run './autogen.sh git' to use it.

shell scripts and makefiles are hard to automate in a portable way, as projects 
use different styles.  Perhaps that's why the Git developers have omitted those.
