[issue2904] Hooks executed on subrepository operations

[IsaacJurado]

New submission from IsaacJurado <diptongo at gmail.com>:

Consider the following scenario: there is a repository A that contains a
subrepository S.  An preupdate hook is defined in repository A's .hg/hgrc. 
If a particular update implies also an update on S, the preupdate hook
defined for A is also executed in the context of repository S.

The only way to prevent this behaviour is to explicitly define an empty
preupdate hook in S's .hg/hgrc.

This pattern happens for all hooks whose triggering operation may imply
subrepository recurson.

Apparently, subrepository recursion merges the repository's .hg/hgrc with
its container's .hg/hgrc.
