The coreutils way does not assume git.

It uses build-aux/vc-list-files, which is a VC-agnostic script.
I require maint.mk rules that process only VC-controlled files.
Recently I changed two of the remaining ones in coreutils'
maint.mk from a find-based approach to the $(VC_LIST_EXCEPT)-based
approach used by all of the other rules.  The reason was to avoid
spending an inordinate amount of time on non-VC'd files that would
be processed by find, but not by $(VC_LIST_EXCEPT).  Processing
non-VC'd files also increases the risk of false-positive matches.
