I'm happy with this now. The only things left are applying ewah on the watch index extension and maybe improve lookup performance a bit. The former needs jk/pack-bitmap graduated. The latter is not urgent. Oh and maybe address "BUGS" section (more like known limitations) in git-file-watcher.txt. For early adopters that fear a buggy file-watcher may cause update loss, set GIT_TEST_WATCHED=1 (or 2). It'll do lstat() to verify file-watcher results (so no perf. gain). Beware of race condition that may lead to false positives, mentioned in 20/26 (maybe I should do something about it).
