It's more than useful, it's mandatory.  It wasn't important for
Aditya's application since he was mainly worried about tracking disk
space usage.  But for anyone who cares about doing quota enforcement,
losing the quota limits when you ran e2fsck is a non-starter.

Just to get this on record, since we discussed this on the weekly
conference call.  I'm currently planning on making quota disabled by
default in e2fsprogs, so that anyone who wants to use quota will have
to use an --enable-quota configure option.  That's because I'm not
completely convinced that quota is fully baked and tested.  After
reviewing Niu's patches, I'll apply them, and that way the quota
feature won't hold up the e2fsprogs 1.42 release.  People who feel
comfortable using it can enable it via --enable-quota, and after we
give it a bit more of a shakedown, we can enable it by default in some
1.42.X maintenance release.

Thanks to Niu and whamcloud for implementing this critically needed
bit of functionality!
