An update on this. I tested out some values:
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=batch add ./
fsync_object_files: 2
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=0 add ./
fsync_object_files: 0
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=1 add ./
fsync_object_files: 1
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=2 add ./
fsync_object_files: 1
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=barf add ./
fatal: bad boolean config value 'barf' for 'core.fsyncobjectfiles'
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=true add ./
fsync_object_files: 1
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=false add ./
fsync_object_files: 0
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=t add ./
fatal: bad boolean config value 't' for 'core.fsyncobjectfiles'
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=y add ./
fatal: bad boolean config value 'y' for 'core.fsyncobjectfiles'
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=yes add ./
fsync_object_files: 1
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=no add ./
fsync_object_files: 0
nksingh@neerajsi-x1:~/src/git$ ./git -c core.fsyncobjectfiles=nope add ./
fatal: bad boolean config value 'nope' for 'core.fsyncobjectfiles'
So I think the code already works like you are suggesting (thanks Junio!).
