If you have an error running 211sync that
inludes lines that look
like these:
error: object file .git/objects/5a/e716b0934b1420a15b8d1a7b689e87635d013d is empty
fatal: loose object 5ae716b0934b1420a15b8d1a7b689e87635d013d (stored in .git/objects/5a/e716b0934b1420a15b8d1a7b689e87635d013d) is corrupt
the following command may fix it (you may want to make a
backup copy of the ic211 directory first, e.g.
cp -r ~/ic211 ~/bkup.ic211):
pushd ~/ic211 ; find .git/objects/ -type f -empty | xargs rm ; git fetch -p ; git fsck --full ; popd
