Adding hook on lookup

[Cédric Krier]

Hi,

Until recently, I used the extension hgwebcachingproxy [1] to maintain
local repositories as cache for our CI machines. But the extension does
not work anymore with latest mercurial versions.
So I found an easy replacement solution to maintain an up to date cache
repository locally by using a hook like this (I do not need automatic
creation):

    [hooks]
    preoutgoing = hg pull

It works very well for `hg clone <path>` but it does not with a revision
`hg clone -r <rev> <path>` (how our CI is cloning).
With revision option, it does not work because a lookup is performed
before the preoutgoing hook is triggered and so if the revision has not
yet been pull, it raises an error.
For now, I patched mercurial to trigger a hook on lookup command. Do you
think it makes sense to have this hook in standard? If yes, what should
be the name of this hook, 'lookup'?
