Christian Couder 277336a5e0 replace: forbid replacing an object with one of a different type
Users replacing an object with one of a different type were not
prevented to do so, even if it was obvious, and stated in the doc,
that bad things would result from doing that.

To avoid mistakes, it is better to just forbid that though.

If -f option, which means '--force', is used, we can allow an object
to be replaced with one of a different type, as the user should know
what (s)he is doing.

If one object is replaced with one of a different type, the only way
to keep the history valid is to also replace all the other objects
that point to the replaced object. That's because:

* Annotated tags contain the type of the tagged object.

* The tree/parent lines in commits must be a tree and commits, resp.

* The object types referred to by trees are specified in the 'mode'
  field:
    100644 and 100755    blob
    160000               commit
    040000               tree
  (these are the only valid modes)

* Blobs don't point at anything.

The doc will be updated in a later patch.
