When using "hash-object -w" to create non-blob objects, it is
generally a good policy to run "git fsck" afterward to make sure the
resulting object is valid. Add a warning to the manpage.
While it at, gently nudge the user of "hash-object -w" toward
higher-level interfaces for creating or modifying trees, commits, and

The usual rule is that with invalid objects (e.g. as detected by "git
fsck"), any non-crash result is acceptable. Garbage in, garbage out.

Probably worth fixing.
I notice that git-hash-object(1) doesn't contain any reference to
git-fsck(1). How about something like this, to start?
Perhaps by default hash-object should automatically fsck the objects
it is asked to create.
