2f28b2bdbb fsync,sync: merge into one source module 
With FEATURE_SYNC_FANCY not set:

function                                             old     new   delta
fsync_main                                           130     123      -7

With FEATURE_SYNC_FANCY set, should be much larger code size savings.

4f74bb6059 fsync,sync: make them similar 
sync: add O_NOCTTY
fsync: drop O_NOATIME, add O_NONBLOCK, set exitcode to 1 if fsync() fails,
    update --help message to be similar to sync.
both: reformat code to minimize "diff -u sync.c fsync.c":
    in particular, they use same open() flags now
