This is now fixed in master.  It turns out that git reset --hard
updates all time stamps, even on files that are not modified.

Unlike git checkout which makes a point of documenting the importance
of preserving/updating timestamps, git reset --hard blindly destroys
all timestamps on not-modified files.

This breaks configure-up-to-date checks, notably lilypond's.
