update $GIT_INDEX_FILE when there are racily clean entries
Traditional "opportunistic index update" done by read-only "diff" and
"status" was about updating cached lstat(2) information in the index for
the next round. We missed another obvious optimization opportunity: when
there are racily clean entries that will cease to be racily clean by
updating $GIT_INDEX_FILE. Detect that case and write $GIT_INDEX_FILE out
to give it a newer timestamp.
Noticed by Lasse Makholm by stracing "git status" in a fresh checkout and
counting the number of open(2) calls.
