Sorry, my wording was imprecise. I meant "Apart from that the configured 
hook was not executed, …".

A diff or diffstat more similarly to Git can be enabled by either

1) setting

[diff]
git = True

or

2) passing "--git" to the "hg diff …" command.

When using hg-git, the similarity config (as described in the other 
answer by Malcolm) must be enabled in addition. The reason is that Git 
doesn’t store copy / rename information (it’s computed on the fly) while 
Mercurial stores it explicitly (when the similarity config is set, 
Mercurial infers and stores the copy / rename information when 
converting from Git to Mercurial).
