mercurial - Can I change the diff tool used in TortoiseHg? -

I use Tortoise HG to make changes. The difference shown in the
command includes a lot of extra / extinction. I configured KDiff3 as an external deaf device.
When I click on the difference icon in the Commit dialog, KDiff3 opens and this comparison is much more intelligent: It detects 'better' what I changed: I moved a block of code , Which resulted in very little addition / deletion.

Since HG "", I was thinking that I can use KDiff3's 'Intelligence' to store these changes. A HG Committed

The proposed solution does not apply to the TortoiseHg Commit Dialog.

Thanks in advance!

It turns out that I misunderstood the behavior of hg commit .
I got a good reply

If you make changes on the internal hg diff with the command or with KDiff3, then it does not make any difference:

Mercurial Just stores the binary difference between the current version of the files and the previous versions of the files.

On merge time, KDiff3's intelligence can still be used.
